2 Chronicles 15:9

2 Chronicles 15:9 Meaning and Commentary

2 Chronicles 15:9

And he gathered all Judah and Benjamin, and the strangers with
them
The proselytes of the gate:

out of Ephraim and Manasseh, and out of Simeon:
out of all the places in those tribes that had come off to him, or had been taken by him; for otherwise these belonged to the ten tribes under the government of Jeroboam, and his successors, and the next clause explains it:

for they fell to him out of Israel abundance, when they saw that the
Lord his God was with him;
as was clear by the victory he gave him over the Ethiopians; after that time many in the above tribes came over to him; the Targum is,

``when they saw the Word of the Lord his God was his help.''

2 Chronicles 15:9 In-Context

7 "But it's different with you: Be strong. Take heart. Payday is coming!"

8 Asa heard the prophecy of Azariah son of Obed, took a deep breath, then rolled up his sleeves, and went to work: He cleaned out the obscene and polluting sacred shrines from the whole country of Judah and Benjamin and from the towns he had taken in the hill country of Ephraim. He spruced up the Altar of God that was in front of The Temple porch.

9 Then he called an assembly for all Judah and Benjamin, including those from Ephraim, Manasseh, and Simeon who were living there at the time (for many from Israel had left their homes and joined forces with Asa when they saw that God was on his side).

10 They all arrived in Jerusalem in the third month of the fifteenth year of Asa's reign

11 for a great assembly of worship. From their earlier plunder they offered sacrifices of 700 oxen and 7,000 sheep for the worship.
