And since Jeroboam and the kings of Israel who followed him would not allow any Levites to serve as priests, most Levites left their towns and pasture lands in Israel and moved to Jerusalem and other towns in Judah.
Hezekiah also appointed other men to take food and supplies to the priests and Levites whose homes were in the pasture land around the towns of Judah. But the priests had to be descendants of Aaron, and the Levites had to be listed in the official records.
Hezekiah divided the priests and Levites into groups, according to their duties. Then he assigned them the responsibilities of offering sacrifices to please the LORD and sacrifices to ask his blessing. He also appointed people to serve at the temple and to sing praises at the temple gates.
Solomon then assigned the priests and the Levites their duties at the temple, and he followed the instructions that his father David had given him. Some of the Levites were to lead music and help the priests in their duties, and others were to guard the temple gates
But only you and your sons can serve as priests at the altar and in the most holy place. Your work as priests is a gift from me, and anyone else who tries to do that work must be put to death.
