Deuteronomy 32:5
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
They have corrupted themselves (note: Heb. he hath corrupted to himself), their spot is not the spot of his children (note: Or, that they are not his children, that is their blot): they are a perverse and crooked generation.
His people have acted corruptly toward Him; the blemish on them is not that of His children, but of a perverse and crooked generation (note: Cited in Philippians 2:15).
