But the word of the Lord came to Shemaiah the man of God, saying,
"Speak to Rehoboam the son of Solomon, king of Judah, and to all Israel in Judah and Benjamin, saying,
'Thus says the Lord: "You shall not go up or fight against your brethren! Let every man return to his house, for this thing is from Me." ' " Therefore they obeyed the words of the Lord, and turned back from attacking Jeroboam.
So Rehoboam dwelt in Jerusalem, and built cities for defense in Judah.
And he built Bethlehem, Etam, Tekoa,
Beth Zur, Sochoh, Adullam,
Gath, Mareshah, Ziph,
Adoraim, Lachish, Azekah,
Zorah, Aijalon, and Hebron, which are in Judah and Benjamin, fortified cities.
And he fortified the strongholds, and put captains in them, and stores of food, oil, and wine.
Also in every city he put shields and spears, and made them very strong, having Judah and Benjamin on his side.
And from all their territories the priests and the Levites who were in all Israel took their stand with him.
For the Levites left their common-lands and their possessions and came to Judah and Jerusalem, for Jeroboam and his sons had rejected them from serving as priests to the Lord.
Then he appointed for himself priests for the high places, for the demons, and the calf idols which he had made.
And after the Levites left, those from all the tribes of Israel, such as set their heart to seek the Lord God of Israel, came to Jerusalem to sacrifice to the Lord God of their fathers.
