Deuteronomy 5:11

5:11 You must not make use of the name of the Lord your God for worthless purposes, for the Lord will not exonerate anyone who abuses his name that way.

Deuteronomy 32:21

32:21 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.
