Deuteronomy 6:13-15

New Century Version

¹³ Respect the Lord your God. You must worship him and make your promises only in his name. ¹⁴ Do not worship other gods as the people around you do, ¹⁵ because the Lord your God is a jealous God. He is present with you, and if you worship other gods, he will become angry with you and destroy you from the earth.
