NET

21 They have made me jealous with false gods, enraging me with their worthless gods; so I will make them jealous with a people they do not recognize, with a nation slow to learn I will enrage them.

Darby

21 They have moved me to jealousy with that which is no God; They have exasperated me with their vanities; And I will move them to jealousy with that which is not a people; With a foolish nation will I provoke them to anger.

KJV

21 They have moved me to jealousy with [that which is] not God; they have provoked me to anger with their vanities: and I will move them to jealousy with [those which are] not a people; I will provoke them to anger with a foolish nation.
