2 Chronicles 15:9
And he gathered all Judah and Benjamin, and the strangers with them out of Ephraim and Manasseh, and out of Simeon: for they fell to him out of Israel in abundance, when they saw that the LORD his God was with him.
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.''
