Pharaoh upbraids Abram for his deception, and doubtless not without reason. He then commands his men to dismiss him and his, unharmed, from the country. These men were probably an escort for his safe conduct out of Egypt. Abram was thus reproved through the mouth of Pharaoh, and will be less hasty in abandoning the land of promise, and betaking himself to carnal resources.

And Pharaoh called Abram, and said,.... Understanding how it was, that Sarai was his wife, which he came at the knowledge of, either by consulting his priests and diviners, as some say, on account of the plagues inflicted; or rather suspecting they were on the account of Sarai, from the nature of them, sent for her, and questioned her about this affair, who confessed the whole matter to him; unless it can be thought that he was warned of God in a dream, as Abimelech was on a like occasion; however he sent for Abram on what intelligence he had, and justly, though gently, reproved him:

what is this that thou hast done unto me? to impose upon me, and deceive me after this manner, by giving out that Sarai was thy sister, when she is thy wife; by which means I have been led to prepare to take her for my wife, and have brought plagues upon myself and family? and thus he resented it as an injury done him, as he well might:

why didst thou not tell me that she was thy wife? when he first took her into his house, and no doubt Abram was present then, and very often afterwards was in company with Pharaoh, and conversed with him, having respect for him for the sake of Sarai, he took to be his sister, and yet would never tell him she was his wife.

And Pharaoh called Abram and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?

12:18 What is this that thou hast done? - What an ill thing; how unbecoming a wife and good man! Why didst thou not tell me that she was thy wife? - Intimating, that if he had known that, he would not have taken her. It is a fault, too common among good people, to entertain suspicions of others beyond what there is cause for. We have often found more of virtue, honour, and conscience in some people, than we thought there was; and it ought to be a pleasure to us to be thus disappointed, as Abram was here, who found Pharaoh to be a better man than he expected.

18-20. Here is a most humiliating rebuke, and Abram deserved it. Had not God interfered, he might have been tempted to stay in Egypt and forget the promise (Ps 105:13, 15). Often still does God rebuke His people and remind them through enemies that this world is not their rest.

12:10-20 There is no state on earth free from trials, nor any character free from blemishes. There was famine in Canaan, the glory of all lands, and unbelief, with the evils it ever brings, in Abram the father of the faithful. Perfect happiness and perfect purity dwell only in heaven. Abram, when he must for a time quit Canaan, goes to Egypt, that he might not seem to look back, and meaning to tarry there no longer than needful. There Abram dissembled his relation to Sarai, equivocated, and taught his wife and his attendants to do so too. He concealed a truth, so as in effect to deny it, and exposed thereby both his wife and the Egyptians to sin. The grace Abram was most noted for, was faith; yet he thus fell through unbelief and distrust of the Divine providence, even after God had appeared to him twice. Alas, what will become of weak faith, when strong faith is thus shaken! If God did not deliver us, many a time, out of straits and distresses which we bring ourselves into, by our own sin and folly, we should be ruined. He deals not with us according to our deserts. Those are happy chastisements that hinder us in a sinful way, and bring us to our duty, particularly to the duty of restoring what we have wrongfully taken or kept. Pharaoh's reproof of Abram was very just: What is this that thou hast done? How unbecoming a wise and good man! If those who profess religion, do that which is unfair and deceptive, especially if they say that which borders upon a lie, they must expect to hear of it; and they have reason to thank those who will tell them of it. The sending away was kind. Pharaoh was so far from any design to kill Abram, as he feared, that he took particular care of him. We often perplex ourselves with fears which are altogether groundless. Many a time we fear where no fear is. Pharaoh charged his men not to hurt Abram in any thing. It is not enough for those in authority, that they do not hurt themselves; they must keep their servants and those about them from doing hurt.
