Deuteronomy 6:16-19 - Exhortation To Obey The Lord Exclusively
16 Ye shall not challenge LORD your God, as ye challenged him in Massah. 17 Ye shall diligently keep the commandments of LORD your God, and his testimonies, and his statutes, which he has commanded thee. 18 And thou shall do that which is right and good in the sight of LORD, that it may be well with thee, and that thou may go in and possess the good land which LORD swore to thy fathers, 19 to thrust out all thine enemies from before thee, as LORD has spoken.
