God is a Jealous God

God is jealous, and the LORD revengeth; the LORD revengeth, and is furious; the LORD will take vengeance on his adversaries, and he reserveth wrath for his enemies. (Nahum 1:2)

For they provoked him to anger with their high places, and moved him to jealousy with their graven images. (Psalm 78:58)

How long, LORD? wilt thou be angry for ever? shall thy jealousy burn like fire? (Psalm 79:5)

Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy 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 (Exodus 20:5)
