Deuteronomy 6:13-15

King James Version

¹³ Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.

¹⁴ Ye 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.
