2 Chronicles 15:8

8 And when Asa heard these words, the prophecy of Oded the prophet, he took courage and removed the vile idols from all the lands of Judah and Benjamin, and from the cities that he had taken in the hill country of Ephraim, and he repaired the altar of Yahweh that was in front of the portico of Yahweh.

2 Chronicles 15:8 Meaning and Commentary

2 Chronicles 15:8

And when Asa heard these words, and the prophecy of Oded the
prophet
Some think that besides the above words of Azariah the son of Oded, a prophecy of Oded his father was related by him, though not recorded; but rather Oded here is the same with the son of Oded; and so the Vulgate Latin and Syriac versions read Azariah the son of Oded; and so does the Alexandrian copy of the Septuagint version:

he took courage, and put away the abominable idols out of all the land
of Judah and Benjamin;
which were abominable to God, and all good men; besides the images and statues he had broken before, he removed other idols that remained, being animated and emboldened by the speech of the prophet:

and out of the cities which he had taken from Mount Ephraim:
the same which his father Abijah had taken from Jeroboam, ( 2 Chronicles 13:19 ) and which perhaps, upon the approach of the Ethiopians, revolted from Asa, or were restored by them to Jeroboam, and Which Asa retook upon his conquest of them:

and renewed the altar of the Lord before the porch of the Lord;
the altar of burnt offering, which had never been repaired since it was made by Solomon; perhaps he anew overlaid it with brass that being worn out, or become very thin in some places.

2 Chronicles 15:8 In-Context

6 Nation was crushed by nation, and city [was] against city, for God threw them into confusion by all [sorts of] trouble.

7 But as for you, be strong and let not your hands be weak, for there is reward for your labor."

8 And when Asa heard these words, the prophecy of Oded the prophet, he took courage and removed the vile idols from all the lands of Judah and Benjamin, and from the cities that he had taken in the hill country of Ephraim, and he repaired the altar of Yahweh that was in front of the portico of Yahweh.

9 And he gathered all Judah and Benjamin and those sojourning with them, from Ephraim, Manasseh, and Simeon, for many had deserted to him from Israel when they saw that Yahweh his God [was] with him.

10 And they were gathered [at] Jerusalem in the third month of the fifteenth year of the reign of Asa.
