Deuteronomy 6:16

14Ye shall not go after other gods, of the gods of the people which are round about you;

15(For the LORD thy God is a jealous God among you) lest the anger of the LORD thy God be kindled against thee, and destroy thee from off the face of the earth.

16Ye shall not tempt the LORD your God, as ye tempted him in Massah.

17Ye shall diligently keep the commandments of the LORD your God, and his testimonies, and his statutes, which he hath commanded thee.

18And thou shalt do that which is right and good in the sight of the LORD: that it may be well with thee, and that thou mayest go in and possess the good land which the LORD sware unto thy fathers.
