'Jealous God' in the Bible

For the Lord your God is a consuming fire, a jealous God.

You shall not worship them or serve them; for I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children, and on the third and the fourth generations of those who hate Me,

for the Lord your God in the midst of 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.
