2 Chronicles 15:8

8 Asa felt brave when he heard these words and the message from Azariah son of Oded the prophet. So he removed the hateful idols from all of Judah and Benjamin and from the towns he had captured in the hills of Ephraim. He repaired the Lord's altar that was in front of the porch of the Temple 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 One nation would destroy another nation, and one city would destroy another city, because God troubled them with all kinds of distress.

7 But you should be strong. Don't give up, because you will get a reward for your good work."

8 Asa felt brave when he heard these words and the message from Azariah son of Oded the prophet. So he removed the hateful idols from all of Judah and Benjamin and from the towns he had captured in the hills of Ephraim. He repaired the Lord's altar that was in front of the porch of the Temple of the Lord.

9 Then Asa gathered all the people from Judah and Benjamin and from the tribes of Ephraim, Manasseh, and Simeon who were living in Judah. Many people came to Asa even from Israel, because they saw that the Lord, Asa's God, was with him.

10 Asa and these people gathered in Jerusalem in the third month of the fifteenth year of Asa's rule.
