Jeremiah 35:2

And the families of the scribes which dwelt at Jabez; the Tirathites, the Shimeathites, and Suchathites. These are the Kenites that came of Hemath, the father of the house of Rechab.

For these Levites, the four chief porters, were in their set office, and were over the chambers and treasuries of the house of God.

And there were narrow windows to the little chambers, and to their posts within the gate round about, and likewise to the arches: and windows were round about inward: and upon each post were palm trees.

And I brought them into the house of the LORD, into the chamber of the sons of Hanan, the son of Igdaliah, a man of God, which was by the chamber of the princes, which was above the chamber of Maaseiah the son of Shallum, the keeper of the door:

And the weight of the nails was fifty shekels of gold. And he overlaid the upper chambers with gold.

And these are the singers, chief of the fathers of the Levites, who remaining in the chambers were free: for they were employed in that work day and night.

Watch ye, and keep them, until ye weigh them before the chief of the priests and the Levites, and chief of the fathers of Israel, at Jerusalem, in the chambers of the house of the LORD.

Thus have we obeyed the voice of Jonadab the son of Rechab our father in all that he hath charged us, to drink no wine all our days, we, our wives, our sons, nor our daughters;

Then Hezekiah commanded to prepare chambers in the house of the LORD; and they prepared them,

Because their office was to wait on the sons of Aaron for the service of the house of the LORD, in the courts, and in the chambers, and in the purifying of all holy things, and the work of the service of the house of God;

And he had prepared for him a great chamber, where aforetime they laid the meat offerings, the frankincense, and the vessels, and the tithes of the corn, the new wine, and the oil, which was commanded to be given to the Levites, and the singers, and the porters; and the offerings of the priests.

And then he built chambers against all the house, five cubits high: and they rested on the house with timber of cedar.
