Deuteronomy 30:2

And shalt return unto the Lord Here is a further description of true repentance. It is a returning unto the Lord, in humiliation, shame, and sorrow, and yet with confidence in him, as our God, with a fixed purpose of obeying him universally and heartily in future. This the Jews did, as a nation, in some measure, after they were carried captive to Babylon, since which time we read nothing of their idolatry. But they degenerated into other sins, which made them reject the Messiah when he was sent to them, for which they are punished to this day, and will be till they repent and be converted, Romans 11:23; Luke 21:24.
