2 Chronicles 15:8

8 When Asa heard these words prophesied by 'Oded the prophet, it gave him courage to throw the disgusting things out of the whole land of Y'hudah and Binyamin and out of the cities he had captured in the hills of Efrayim; he also renewed the altar of ADONAI which was in front of the vestibule of ADONAI.

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 so that they were shattered to pieces, nation against nation and city against city, as God troubled them with every kind of distress.
7 But you, be strong, and don't slack off; for your work will be rewarded."
8 When Asa heard these words prophesied by 'Oded the prophet, it gave him courage to throw the disgusting things out of the whole land of Y'hudah and Binyamin and out of the cities he had captured in the hills of Efrayim; he also renewed the altar of ADONAI which was in front of the vestibule of ADONAI.
9 Then he gathered all Y'hudah and Binyamin, along with those from Efrayim, M'nasheh and Shim'on who were staying with him (for they had defected to him in large numbers upon seeing that ADONAI his God was with him).
10 They assembled together at Yerushalayim in the third month of the fifteenth year of Asa's reign.
