2 Chronicles 15:8

8 And when Asa had heard this thing, that is, the words and [the] prophecy of Azariah, the son of Oded, the prophet, he was comforted, and he did away all the idols from all the land of Judah and of Benjamin, and from the cities which he had taken of the hill of Ephraim. And he hallowed the altar of the Lord, that was before the porch of the house of the Lord. (And when Asa had heard this, that is, the words and the prophecy of the prophet Azariah, the son of Oded, he was strengthened, or encouraged, and he did away all the idols from all the land of Judah and of Benjamin, and from the cities which he had taken in the hill country of Ephraim. And he repaired the altar of the Lord, that was in front of the vestibule of the House of the Lord.)

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 For folk shall fight against folk, and a city against a city, for the Lord shall disturb them in all anguish; (And nation fought against nation, and a city against a city, for the Lord troubled them with all kinds of anguish;)

7 but be ye comforted, and your hands be not slacked; for meed shall be to your work. (but be ye strengthened, and do not let your hands be limp; for your work shall be rewarded.)

8 And when Asa had heard this thing, that is, the words and [the] prophecy of Azariah, the son of Oded, the prophet, he was comforted, and he did away all the idols from all the land of Judah and of Benjamin, and from the cities which he had taken of the hill of Ephraim. And he hallowed the altar of the Lord, that was before the porch of the house of the Lord. (And when Asa had heard this, that is, the words and the prophecy of the prophet Azariah, the son of Oded, he was strengthened, or encouraged, and he did away all the idols from all the land of Judah and of Benjamin, and from the cities which he had taken in the hill country of Ephraim. And he repaired the altar of the Lord, that was in front of the vestibule of the House of the Lord.)

9 And he gathered together all Judah and Benjamin, and with them the comelings of Ephraim, and of Manasseh, and of Simeon (and with them the newcomers from Ephraim, and Manasseh, and Simeon); for many of Israel, seeing that his Lord God was with him, fled over to him.

10 And when they had come into Jerusalem, in the third month, in the fifteen year of the realm of Asa,
