Numbers 22:31

31. Opened the eyes His natural eyes, which up to this time had been unable to see the angel. Luke 24:16, note. Says Hengstenberg, “This is a statement which cannot possibly be understood of any thing but the inward eye.” Query: Did the ass also see the angel with his inward eye? Was the beast in an ecstatic state? The literal exegesis is far more rational than that which reduces this whole affair to a phantasm supernaturally wrought in the mind of the man and the beast.

Fell flat on his face Hebrew, he bowed himself to his face, that is, either upon his own face, or to the face of the angel, in adoration. “Adored him, [falling,] prone to the ground.” Vulgate. “He bowed, and worshipped upon his face.” Targum of Onkelos.
