2 Chronicles 15:8

8 When Asa heard these words and the prophecy of [Azariah son of] Oded the prophet, he took courage and removed the detestable idols from the whole land of Judah and Benjamin and from the cities he had captured in the hill country of Ephraim. He renovated the altar of the Lord that was in front of the vestibule of the Lord's [temple].

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 by city, for God troubled them with every possible distress.
7 But as for you, be strong; don't be discouraged, for your work has a reward."
8 When Asa heard these words and the prophecy of [Azariah son of] Oded the prophet, he took courage and removed the detestable idols from the whole land of Judah and Benjamin and from the cities he had captured in the hill country of Ephraim. He renovated the altar of the Lord that was in front of the vestibule of the Lord's [temple].
9 Then he gathered all Judah and Benjamin, as well as those from [the tribes of] Ephraim, Manasseh, and Simeon who had settled among them, for they had defected to him from Israel in great numbers when they saw that the Lord his God was with him.
10 They were gathered in Jerusalem in the third month of the fifteenth year of Asa's reign.
