Deuteronomy 31:21

New American Standard Bible

²¹ Then it will come about, ^(A)when many evils and troubles find them, that this song will testify before them as a witness (for it shall not be forgotten from the mouth of their ^[a]descendants); for ^(B)I know their inclination which they are ^[b]developing today, before I bring them into the land which I swore.”
