In the inn - Or "resting place." See Genesis 42:27 note.

Met him, and sought to kill him - Moses was attacked by a sudden and dangerous illness, which he knew was inflicted by God. The word "sought to kill" implies that the sickness, whatever might be its nature, was one which threatened death had it not been averted by a timely act. Zipporah believed that the illness of Moses was due to his having neglected the duty of an Israelite, and to his not having circumcised his own son; the delay was probably owing to her own not unnatural repugnance to a rite, which though practiced by the Egyptians, was not adopted generally in the East, even by the descendants of Abraham and Keturah. Moses appears to have been utterly prostrate and unable to perform the rite himself.

By the way in the inn - See Clarke's note on Genesis 42:27. The account in this and the following verse is very obscure. Some suppose that the Exodus 4:23 is not a part of the message to Pharaoh, but was spoken by the Lord to Moses; and that the whole may be thus paraphrased: "And I have said unto thee, (Moses), Send forth שלח shallach, my son, (Gershom, by circumcising him), that he may serve me, (which he cannot do till entered into the covenant by circumcision), but thou hast refused to send him forth; behold, (therefore), I will slay thy son, thy first-born. And it came to pass by the way in the inn, (when he was on his journey to Egypt), that Jehovah met him, and sought (threatened) to kill him (Gershom). Then Zipporah took a sharp stone, and cut away the foreskin of her son, and caused it to touch his feet, (Jehovah's, who probably appeared in a bodily shape; the Septuagint call him the Angel of the Lord), and said unto him, A spouse by blood art thou unto me. Then he (Jehovah) ceased from him (Gershom). Then she said, A spouse by blood art thou unto me, because of this circumcision." That is, I who am an alien have entered as fully into covenant with thee by doing this act, as my son has on whom this act has been performed.

The meaning of the whole passage seems to be this: - The son of Moses, Gershom or Eliezer, (for it does not appear which), had not been circumcised, though it would seem that God had ordered the father to do it; but as he had neglected this, therefore Jehovah was about to have slain the child, because not in covenant with him by circumcision, and thus he intended to have punished the disobedience of the father by the natural death of his son. Zipporah, getting acquainted with the nature of the case and the danger to which her first-born was exposed, took a sharp stone and cut off the foreskin of her son. By this act the displeasure of the Lord was turned aside, and Zipporah considered herself as now allied to God because of this circumcision. According to the law, (Genesis 17:14), the uncircumcised child was to be cut off from his people, so that there should be no inheritance for that branch of the family in Israel. Moses therefore, for neglecting to circumcise the child, exposed him to this cutting off, and it was but barely prevented by the prompt obedience of Zipporah. As circumcision was the seal of that justification by faith which comes through Christ, Moses by neglecting it gave a very bad example, and God was about to proceed against him with that severity which the law required.

The sharp stone mentioned Exodus 4:25 was probably a knife made of flint, for such were anciently used, even where knives of metal might be had, for every kind of operation about the human body, such as embowelling for the purpose of embalming, circumcision, etc. Ancient authors are full of proofs of these facts. See Clarke's note on Genesis 50:2. It is probable that Zipporah, being alarmed by this circumstance, and fearing worse evils, took the resolution to return to her father's house with her two sons. See Exodus 18:1, etc.

And it came to pass by the way, in the inn,.... As Moses and his family were travelling in their way to Egypt, at an inn where they stopped for the refreshment of themselves and cattle, or in order to lodge all night: so it was, that the Lord met him, and sought to kill him; not the uncircumcised son of Moses, as some think, but Moses himself, who had neglected the circumcision of his son; that from the context, and the fact of Zipporah, after related, seems to be the reason of the divine displeasure, and not his bringing his family with him, supposed to be an hinderance of him in his work, nor of his staying too long at the inn, and not hastening his journey, which are the reasons given by some: and Moses's neglect of circumcision was not owing to the disuse of it among the Midianites, who being the descendants of Abraham, it is highly probable they retained this rite, and that it was used in Jethro's family, since Zipporah well understood the nature of it, and how to perform it; and it looks as if her eldest son had been circumcised before, seeing only one was now circumcised by her; but the Midianites perhaps followed the same practice as the Ishmaelites did, who were their neighbours, and the descendants of Abraham also, who deferred it till their children were thirteen years of age; or if this child was a very young one, it might have been put off, because of the journey they were just about to take, and purposing to do it when come into Egypt; but this was resented by the Lord in Moses, who had such knowledge of the law of God; and this displeasure of Jehovah might be signified either by inflicting some disease upon him, as Aben Ezra and Kimchi think, which threatened him with death, or by appearing in a terrible manner, as the angel of the Lord did to Balaam, with a drawn sword in his hand.

But if Moses was to carry out the divine commission with success, he must first of all prove himself to be a faithful servant of Jehovah in his own house. This he was to learn from the occurrence at the inn: an occurrence which has many obscurities on account of the brevity of the narrative, and has received many different interpretations. When Moses was on the way, Jehovah met him at the resting-place (מלון, see Genesis 42:27), and sought to kill him. In what manner, is not stated: whether by a sudden seizure with some fatal disease, or, what is more probable, by some act proceeding directly from Himself, which threatened Moses with death. This hostile attitude on the part of God was occasioned by his neglect to circumcise his son; for, as soon as Zipporah cut off (circumcised) the foreskin of her son with a stone, Jehovah let him go. צור equals צוּר, a rock, or stone, here a stone knife, with which, according to hereditary custom, the circumcision commanded by Joshua was also performed; not, however, because "stone knives were regarded as less dangerous than those of metal," nor because "for symbolical reasons preference was given to them, as a simple production of nature, over the metal knives that had been prepared by human hands and were applied to daily use." For if the Jews had detected any religious or symbolical meaning in stone, they would never have given it up for iron or steel, but would have retained it, like the Ethiopian tribe of the Alnaii, who used stone knives for that purpose as late as 150 years ago; whereas, in the Talmud, the use of iron or steel knives for the purpose of circumcision is spoken of, as though they were universally employed. Stone knives belong to a time anterior to the manufacture of iron or steel; and wherever they were employed at a later period, this arose from a devoted adherence to the older and simpler custom (see my Commentary on Joshua 5:2). From the word "her son," it is evident that Zipporah only circumcised one of the two sons of Moses (Exodus 4:20); so that the other, not doubt the elder, had already been circumcised in accordance with the law. Circumcision had been enjoined upon Abraham by Jehovah as a covenant sign for all his descendants; and the sentence of death was pronounced upon any neglect of it, as being a breach of the covenant (Genesis 17:14). Although in this passage it is the uncircumcised themselves who are threatened with death, yet in the case of children the punishment fell upon the parents, and first of all upon the father, who had neglected to keep the commandment of God. Now, though Moses had probably omitted circumcision simply from regard to his Midianitish wife, who disliked this operation, he had been guilty of a capital crime, which God could not pass over in the case of one whom He had chosen to be His messenger, to establish His covenant with Israel. Hence He threatened him with death, to bring him to a consciousness of his sin, either by the voice of conscience or by some word which accompanied His attack upon Moses; and also to show him with what earnestness God demanded the keeping of His commandments. Still He did not kill him; for his sin had sprung from weakness of the flesh, from a sinful yielding to his wife, which could both be explained and excused on account of his position in the Midianite's house. That Zipporah's dislike to circumcision had been the cause of the omission, has been justly inferred by commentators from the fact, that on Jehovah's attack upon Moses, she proceeded at once to perform what had been neglected, and, as it seems, with inward repugnance. The expression, "She threw (the foreskin of her son) at his (Moses') feet," points to this (ל הגּיע, as in Isaiah 25:12). The suffix in רגליו (his feet) cannot refer to the son, not only because such an allusion would give no reasonable sense, but also because the suffix refers to Moses in the immediate context, both before (in המיתו, Exodus 4:24) and after (in ממּנּוּ, Exodus 4:26); and therefore it is simpler to refer it to Moses here. From this it follows, then, that the words, "a blood-bridegroom art thou to me," were addressed to Moses, and not to the boy. Zipporah calls Moses a blood-bridegroom, "because she had been compelled, as it were, to acquire and purchase him anew as a husband by shedding the blood of her son" (Glass). "Moses had been as good as taken from her by the deadly attack which had been made upon him. She purchased his life by the blood of her son; she received him back, as it were, from the dead, and married him anew; he was, in fact, a bridegroom of blood to her" (Kurtz). This she said, as the historian adds, after God had let Moses, go, למּוּלות, "with reference to the circumcisions." The plural is used quite generally and indefinitely, as Zipporah referred not merely to this one instance, but to circumcision generally. Moses was apparently induced by what had occurred to decide not to take his wife and children with him to Egypt, but to send them back to his father-in-law. We may infer this from the fact, that it was not till after Israel had arrived at Sinai that he brought them to him again (Exodus 18:2).

And it came to pass by the way in the inn, that the LORD met him, and {l} sought to kill him.

(l) God punished him with sickness for neglecting his ordinances.

4:24 It seems the sin of Moses, was neglecting to circumcise his son, which perhaps was the effect of his being unequally yoked with a Midianite, who was too indulgent of her child, and Moses so of her. The Lord met him, and, probably, by a sword in an angel's hand, sought to kill him - This was a great change. Very lately God was conversing with him as a friend, and now coming forth against him as an enemy. In this case of necessity Zipporah herself circumcised the child without delay; whether with passionate words, expressing the dislike of the ordinance itself, or at least the administration of it to so young a child.

[3] kill him

(Cf) Gen 17:14 The context (Gen 4:25) interprets v. 25. Moses was forgetful of the very foundation sign of Israel's covenant relation to Jehovah. On the eve of delivering Israel he was thus reminded that without circumcision an Israelite was cut off from the covenant. Josh 5:3-9.

24. inn-Hebrew, "a halting place for the night."

the Lord met him, and sought to kill him-that is, he was either overwhelmed with mental distress or overtaken by a sudden and dangerous malady. The narrative is obscure, but the meaning seems to be, that, led during his illness to a strict self-examination, he was deeply pained and grieved at the thought of having, to please his wife, postponed or neglected the circumcision of one of his sons, probably the younger. To dishonor that sign and seal of the covenant was criminal in any Hebrew, peculiarly so in one destined to be the leader and deliverer of the Hebrews; and he seems to have felt his sickness as a merited chastisement for his sinful omission. Concerned for her husband's safety, Zipporah overcomes her maternal feelings of aversion to the painful rite, performs herself, by means of one of the sharp flints with which that part of the desert abounds, an operation which her husband, on whom the duty devolved, was unable to do, and having brought the bloody evidence, exclaimed in the painful excitement of her feelings that from love to him she had risked the life of her child [Calvin, Bullinger, Rosenmuller].

4:24-31 God met Moses in anger. The Lord threatened him with death or sent sickness upon him, as the punishment of his having neglected to circumcise his son. When God discovers to us what is amiss in our lives, we must give all diligence to amend it speedily. This is the voice of every rod; it calls us to return to Him that smites us. God sent Aaron to meet Moses. The more they saw of God's bringing them together, the more pleasant their interview was. The elders of Israel met them in faith, and were ready to obey them. It often happens, that less difficulty is found than was expected, in such undertakings as are according to the will of God, and for his glory. Let us but arise and try at our proper work, the Lord will be with us and prosper us. If Israel welcomed the tidings of their deliverance, and worshipped the Lord, how should we welcome the glad tidings of redemption, embrace it in faith, and adore the Redeemer!
