Melachim Bais 21:4 Meaning and Commentary

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.

Melachim Bais 21:4 In-Context

2 And he did that which was rah in the eyes of Hashem, after the to’avot of the Goyim, whom Hashem drove out before the Bnei Yisroel.

3 For he built up again the [idolatrous] high places which Chizkiyah aviv had destroyed; and he reared up mizbechot for Ba’al, and made Asherah, as did Ach’av Melech Yisroel; and bowed down in worship to kol Tzava HaShomayim, and served them.

4 And he built mizbechot in the Beis Hashem, of which Hashem said, In Yerushalayim will I put Shmi (My Name).

5 And he built mizbechot for kol Tzava HaShomayim in the two khatzerot (courtyards) of the Beis Hashem.

6 And he made bno pass through the eish, and practiced sorcery, and witchcraft, and dealt with familiar spirits [i.e., he consulted mediums] and spiritists; he wrought much rah in the eyes of Hashem, to provoke Him to anger.
