For the LORD your God, who is among you, is a jealous God. Otherwise the anger of the LORD your God will be kindled against you, and He will wipe you off the face of the earth.
Jewish Publication Society of America Version (JPS1917) - Deuteronomy 6:15 >for a jealous God, even the LORD thy God, is in the midst of thee; lest the anger of the LORD thy God be kindled against thee, and He destroy thee from off the face of the earth.
