Deuteronomy 6:13-15
Deuteronomy 6:13-15 ESV
It is the LORD your God you shall fear. Him you shall serve and by his name you shall swear. You shall not go after other gods, the gods of the peoples who are around you— for the LORD your God in your midst is a jealous God—lest the anger of the LORD your God be kindled against you, and he destroy you from off the face of the earth.
