'Jealous God' in the Bible

Indeed, the LORD your God is a consuming fire. He is a jealous God."

You are not to bow down to them in worship or serve them, because I, the LORD your God, am a jealous God, visiting the guilt of parents on children, to the third and fourth generation of those who hate me,

For the LORD your God who is among you is a jealous God. He will turn his anger against you and destroy you from the surface of the land."
