Deuteronomy 6:14-16

14Ye shall not go after other 1gods, of the 2gods of the peoples that are round about you;

15for Jehovah thy 3God is a jealous 4God in thy midst; lest the anger of Jehovah thy 5God be kindled against thee, and he destroy thee from the face of the earth.

16Ye shall not tempt Jehovah your 6God, as ye tempted him in Massah.
