Deuteronomy 6:13-15

Authorized (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.
