Charles Ellicott Commentary Deuteronomy 30:8

"And thou shalt return and obey the voice of Jehovah, and do all his commandments which I command thee this day." — Deuteronomy 30:8 (ASV)

And thou shalt return and ... do all his commandments. —It is as certain as anything can be in this world that the laws of Deuteronomy have never been kept perfectly. The minute observances of the Talmudical system took the heart and spirit out of the law of Moses. Christians do not profess to obey any commandments but those which are called moral. If the Law itself is to be fulfilled, a restoration of Israel would seem to be necessary.
