And he took the calf which they had made, and burnt it in the fire, and ground it to powder, and scattered it upon the water, and made the children of Israel drink of it.
All Commentaries on Exodus 32:20 Go To Exodus 32
Augustine of Hippo
AD 430
Therefore perhaps that calf, being ground to powder, was cast into the water and given to the children of Israel to drink, that so the body of ungodliness might be swallowed up by Israel.
