For they went and served other gods, and worshipped them, gods whom they knew not, and whom he had not given unto them:
Context
25 Then men will say, “Because they abandoned the covenant of the LORD, the God of their fathers, which he made with them when he brought them out of the land of Egypt,
26 and went and served other gods and worshiped them, gods that they didn’t know and that he had not given to them.
27 Therefore the LORD’s anger burned against this land, to bring on it all the curses that are written in this book.
