The angel of the Lord - Generally supposed to have been the same that appeared to Moses, Joshua, Gideon, etc., and no other than the second person of the ever-blessed Trinity.

And the angel of the Lord appeared unto the woman,.... According to Josephus (k), it was in a plain without the city; and that he appeared in the form of a man is certain from Judges 13:6 but was not a mere man, a prophet of the Lord, nor a created angel, but the uncreated one, the Angel of the covenant, the Son and Word of God, who often appeared in an human form; since his name is said to be "Wonderful", and he to do wonderful things, and is called "Jehovah", Judges 13:18,

and said unto her, behold now, thou art barren, and bearest not; barren at that time, and so she had been ever since she was married to that time; and this is observed, that it might appear the more wonderful that she should after this have a child:

but thou shalt conceive, and bear a son; which to do, must be ascribed to divine power, that one in her circumstances should bear a son; as the prediction of it was owing to divine omniscience, and a proof of it.

(k) Antiqu. l. 5. c. 8. sect. 2.

And the angel of the LORD appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not: but thou shalt conceive, and bear a son.

13:3 The angel - The Son of God, yet distinguished from the Lord, because he appeared here in the form of a servant, as a messenger sent from God. The great Redeemer did in a particular manner concern himself about this typical redeemer.

3. the angel of the Lord-The messenger of the covenant, the divine personage who made so many remarkable appearances of a similar kind already described.

13:1-7 Israel did evil: then God delivered them again into the hands of the Philistines. When Israel was in this distress, Samson was born. His parents had been long childless. Many eminent persons were born of such mothers. Mercies long waited for, often prove signal mercies; and by them others may be encouraged to continue their hope in God's mercy. The angel notices her affliction. God often sends comfort to his people very seasonably, when they feel their troubles most. This deliverer of Israel must be devoted to God. Manoah's wife was satisfied that the messenger was of God. She gave her husband a particular account, both of the promise and of the precept. Husbands and wives should tell each other their experiences of communion with God, and their improvements in acquaintance with him, that they may help each other in the way that is holy.
