2 Kings 21:4

And he built altars in the house of the Lord
In the holy place, as distinct from the courts in the next verse; and these were sacred to the idols of the Gentiles:

of which the Lord said, in Jerusalem will I put my name;
in the temple there, devoted to his service, called by his name, and where his name was called upon, see ( Deuteronomy 12:5 ) ( 16:6 ) and to erect altars to idols here must be very abominable to him.
