'Jealous God' in the Bible

For the LORD your God is a consuming fire, even a jealous God.

You shall not bow down yourself unto them, nor serve them: for I the LORD your God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,

(For the LORD your God is a jealous God among you) lest the anger of the LORD your God be kindled against you, and destroy you from off the face of the earth.
