Deuteronomy 6:13-15

Complete Jewish Bible

¹³ You are to fear Adonai your God, serve him and swear by his name. ¹⁴ You are not to follow other gods, chosen from the gods of the peoples around you; ¹⁵ because Adonai, your God, who is here with you, is a jealous God. If you do, the anger of Adonai your God will flare up against you and he will destroy you from the face of the earth.
