In this eventful moment, when Isaac lay bound like a lamb upon the altar, about to receive the fatal stroke, the angel of the Lord called down from heaven to Abraham to stop, and do his son no harm. For the Lord now knew that Abraham was אלהים ירא God-fearing, and that his obedience of faith did extend even to the sacrifice of his own beloved son. The sacrifice was already accomplished in his heart, and he had fully satisfied the requirements of God. He was not to slay his son: therefore God prevented the outward fulfilment of the sacrifice by an immediate interposition, and showed him a ram, which he saw, probably being led to look round through a rustling behind him, with its horns fast in a thicket (אחר adv. behind, in the background); and as an offering provided by God Himself, he sacrificed it instead of his son.
