'Obey the Voice of the Lord' in the Bible

You shall therefore obey the voice of the LORD your God, and do his commandments and his statutes, which I command you this day.

And you shall be left few in number, whereas you were as the stars of heaven for multitude; because you would not obey the voice of the LORD your God.

And you shall return and obey the voice of the LORD, and do all his commandments which I command you this day.
