(11) The angel of the Lord.--Up to this point, the narrative had been Elohistic, but it is the angel of Jehovah who interferes to stop the sacrifice (see on Genesis 16:7).

Verse 11. - And the angel of the Lord - Maleach Jehovah (vide Genesis 16:7); introduced into the narrative at this point not as a Jehovistic alteration (Bleek, Kalisch, et alii), but because the God of redemption now interposes for the deliverance of both Isaac and Abraham (Hengetenberg) - called unto him out of heaven, and said, Abraham, Abraham (the repetition denotes urgency, as contrasted with Ver. 1): and he said, Here am I.

22:11-14 It was not God's intention that Isaac should actually be sacrificed, yet nobler blood than that of animals, in due time, was to be shed for sin, even the blood of the only begotten Son of God. But in the mean while God would not in any case have human sacrifices used. Another sacrifice is provided. Reference must be had to the promised Messiah, the blessed Seed. Christ was sacrificed in our stead, as this ram instead of Isaac, and his death was our discharge. And observe, that the temple, the place of sacrifice, was afterwards built upon this same mount Moriah; and Calvary, where Christ was crucified, was near. A new name was given to that place, for the encouragement of all believers, to the end of the world, cheerfully to trust in God, and obey him. Jehovah-jireh, the Lord will provide; probably alluding to what Abraham had said, God will provide himself a lamb. The Lord will always have his eye upon his people, in their straits and distresses, that he may give them seasonable help.And the Angel of the Lord called unto him out of heaven,.... Not a created angel, but the eternal one, the Son of God, who perhaps appeared in an human form, and spoke with an articulate voice, as be frequently did; for that this was a divine Person is clear from his swearing by himself, and renewing the promise unto Abraham, Genesis 22:16,

and said, Abraham, Abraham; the repeating his name denotes haste to prevent the slaughter of his son, which was just upon the point of doing, and in which Abraham was not dilatory, but ready to make quick dispatch; and therefore with the greater eagerness and vehemency the angel calls him by name, and doubles it, to raise a quick and immediate attention to him, which it did:

and he said, here am I: ready to hearken to what shall be said, and to obey what should be ordered; see Gill on Genesis 22:1.
