Exodus 23:13 (AV)
And in all things that I have said unto you be circumspect:
and make no mention of the name of other gods,
neither let it be heard out of thy mouth.

Psalm 44:20-21 (AV)
If we have forgotten the name of our God,
or stretched out our hands to a strange god;
Shall not God search this out?
for he knoweth the secrets of the heart.
