Charles Ellicott Commentary Deuteronomy 4:28

"And there ye shall serve gods, the work of men`s hands, wood and stone, which neither see, nor hear, nor eat, nor smell." — Deuteronomy 4:28 (ASV)

And there you shall serve gods, the work of men’s hands. —That is, “you shall be in bondage to them,” being ruled by their worshippers. And so Rashi explains it. Captivity was the means of eradicating idolatry from Israel rather than encouraging it. But the cause of a people and its idols is so constantly identified in the Old Testament, that those who are in bondage to a nation may naturally be described as in bondage to its gods. The gods were even held to be sharers in the captivity of the nation. It is said of Bel and Nebo, in Isaiah 46:2, They could not deliver ... but themselves are gone into captivity.
