John Gill Commentary Deuteronomy 6:14

"Ye shall not go after other gods, of the gods of the peoples that are round about you;" — Deuteronomy 6:14 (ASV)

You shall not go after other gods
To serve and worship them, and swear by them; and which indeed are no gods, only nominal and fictitious ones; idols which are nothing in the world, and ought to have no veneration and adoration given them; to go after them is to worship them, and this is to depart from the true God, and go a whoring after false deities:

of the gods of the people which are round about you ;
the gods of the Edomites, Ammonites, Moabites, Philistines, and Egyptians; all of which had their peculiar deities.
