Matthew Henry Commentary Genesis 22:11-14

"And the angel of Jehovah called unto him out of heaven, and said, Abraham, Abraham. And he said, Here I am. And he said, Lay not thy hand upon the lad, neither do thou anything unto him. For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me. And Abraham lifted up his eyes, and looked, and behold, behind [him] a ram caught in the thicket by his horns. And Abraham went and took the ram, and offered him up for a burnt-offering in the stead of his son. And Abraham called the name of that place Jehovah-jireh. As it is said to this day, In the mount of Jehovah it shall be provided." — Genesis 22:11-14 (ASV)

It was not God's intention that Isaac should actually be sacrificed. Yet, in due time, nobler blood than that of animals was to be shed for sin—even the blood of the only begotten Son of God. In the meantime, however, God would not in any case allow human sacrifices; another sacrifice is provided.

This refers to the promised Messiah, the blessed Seed. Christ was sacrificed in our place, just as this ram was sacrificed instead of Isaac, and His death was our acquittal. 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, to trust cheerfully in God and obey Him. The name was Jehovah-jireh, meaning, "The Lord will provide." This probably alludes to what Abraham had said: God will provide himself a lamb. The Lord will always have His eye upon His people in their hardships and distresses, so that He may give them timely help.
