Divrey Hayamim Bais 31:1 Meaning and Commentary

2 Chronicles 31:1

Now when all this was finished
The temple cleansed, the priests and Levites sanctified, the passover and feast of unleavened bread observed, and other seven days of rejoicing kept:

all Israel that were present went out to the cities of Judah, and brake
the images in pieces, and cut down the groves, and threw down the high
places and the altars out of all Judah and Benjamin;
which had been erected by Ahaz, ( 2 Chronicles 28:2 2 Chronicles 28:25 ) at or about this time also the brasen serpent was broke to pieces, ( 2 Kings 18:4 ) ,

in Ephraim also and Manasseh, until they had utterly destroyed them
all;
which must be understood of such cities in those tribes that had been taken in former times by the kings of Judah from the kings of Israel; or such as were now in the hands of the Assyrians, who might not concern themselves in matters of religion; or this might be done at the connivance of Hoshea king of Israel, who had no regard to any other idolatry than the worship of the calves; and besides, having met with trouble from the Assyrians, and fearing more, might be willing to have his kingdom cleared of idolatry, in hope the divine displeasure would be removed:

then all the children of Israel returned every man to his possession
into their own cities;
and not till then, when all monuments of idolatry were removed.

Divrey Hayamim Bais 31:1 In-Context

1 1 Now when all this was completed, kol Yisroel that were present went out to the towns of Yehudah, and smashed the matzevot, and cut down the Asherim, and threw down the high places and the mizbechot throughout kol Yehudah and Binyamin, in Ephrayim also and Menasheh, until they had utterly destroyed them all. Then all the Bnei Yisroel returned, every ish to his achuzzah, into their own towns.

2 And Chizkiyah appointed the machlekot of the Kohanim and the Levi’im after their divisions, every ish according to his avodas service, the Kohanim and Levi’im for olah and for shelamim, to minister, to give thanks, to praise in the Sh’arei Machanot Hashem.

3 A gift from HaMelech, from his own possessions, was for the olot, for the boker and erev olot, and the olot for the Shabbatot, and for Rosh Chodesh, and for the Mo’adim, as it is written in the Torat Hashem.

4 Moreover he commanded HaAm that dwelt in Yerushalayim to give the menat HaKohanim v’HaLevi’im (support of the Kohanim and the Levi’im), that they might strengthen themselves in the Torat Hashem.

5 And as soon as the devar went out, the Bnei Yisroel brought in abundance the reshit of dagan, tirosh, and yitzhar (pure olive oil), and devash, and of all the increase of the sadeh; and the ma’aser (tithe) of all things they brought in abundantly.
