Deuteronomy 12:30

Take heed to thyself, that thou be not snared by following
them
Their examples and customs, and so be drawn into the same idolatrous practices; see ( Psalms 106:35 Psalms 106:36 ) , after that they be destroyed from before thee; for their idolatries and other sins:

and that thou inquire not after their gods;
what they were, their names, forms, and figures:

saying, how did these nations serve their gods?
what was the manner of worship they gave them? what rites, customs, and ceremonies did they use in their adoration of them?

even so will I do likewise;
or however, if this was not determined on when the inquiries were made, there was danger that this would be the result of them, and therefore the caution is given.
