Matthew Poole and continuators on Genesis 22:13

13 And Abraham lifted up his eyes and looked, and behold, behind him a ram caught in a thicket by his horns: and Abraham went, and took the ram, and offered him up for a burntoffering in the stead of his son.

Which way he looked either because the voice came that way: Or because he heard the noise made by the motion of the Ram in the thicket.

Which had gone astray from the rest of the Flock, and whose errours were directed hither by Gods wise and powerful Providence, and being young, though horned, it might be called either Lamb, as v. 7. or Ram, as it is here. There needs no curious enquiry, how he could offer up that to God which was not his own, both because it was found in a publick place, and in all probability utterly lost to his owner, and because he had no doubt a warrant and inspiration for it from the great Lord and supreme owner of all things.
