Genesis 22:13

“And Abraham lifted up his eyes, etc.] They were before fixed upon his son lying upon the altar, and intent upon that part he was going to thrust his knife into; but hearing a voice from heaven above him, he lift up his eyes thitherward: and looked, and, behold, behind [him] a ram caught in a thicket by his horns; the ram making a noise and rustling among the bushes behind the place where Abraham was, he turned himself, and looked and saw it: the Targum of Onkelos introduces the clause thus, “after these things”; and so the Arabic version: after Abraham had heard the voice of the angel, and had lift up his eyes to heaven, he was directed to look behind him; and both that and the Targum of…”

“Abraham lifted up his eyes . . . and behold . . . a ram, &c.--No method was more admirably calculated to give the patriarch a distinct idea of the purpose of grace than this scenic representation: and hence our Lord's allusion to it (Joh 8:56). Next: Genesis Chapter 23”

“22:13 God provided a ram caught by its horns in a thicket for the sacrifice. God graciously allowed Abraham to substitute an animal sacrifice in place of Isaac. Later, all Israel would offer animals to the Lord, knowing that God’s grace had provided this substitution (Exod 29:10; Lev 4:15; 16:20-22). In the New Testament, God substituted his only son for all humanity; the perfect sacrifice was made once and for all (Isa 53:6, 10; John 1:29; Heb 7:27; 10:1-14; 1 Pet 3:18).”
