2 Chronicles 29:25–34

²⁵And he appointeth the Levites in the house of Jehovah with cymbals, with psalteries, and with harps, by the command of David, and of Gad, seer of the king, and of Nathan the prophet, for by the hand of Jehovah is the command, by the hand of His prophets; ²⁶and the Levites stand with the instruments of David, and the priests with the trumpets. ²⁷And Hezekiah saith to cause the burnt-offering to ascend on the altar; and at the time the burnt-offering began—began the song of Jehovah, and the trumpets, even by the hands of the instruments of David king of Israel. ²⁸And all the assembly are doing obeisance, and the singers singing, and the trumpeters blowing; the whole is till the completion of the burnt-offering. ²⁹And at the completion of the offering up bowed have the king and all those found with him, and do obeisance. ³⁰And Hezekiah the king saith, and the princes, to the Levites to give praise to Jehovah in the words of David, and of Asaph the seer, and they praise—unto joy, and they bow, and do obeisance. ³¹And Hezekiah answereth and saith, ‘Now ye have filled your hand to Jehovah, come nigh, and bring in sacrifices and thank-offerings to the house of Jehovah;’ and the assembly bring in sacrifices and thank-offerings, and every willing-hearted one—burnt-offerings. ³²And the number of the burnt-offerings that the assembly have brought in, is seventy oxen, a hundred rams, lambs two hundred; for a burnt-offering to Jehovah are all these. ³³And the sanctified things are oxen six hundred, and sheep three thousand. ³⁴Only, the priests have become few, and have not been able to strip the whole of the burnt-offerings, and their brethren the Levites strengthen them till the completion of the work, and till the priests sanctify themselves, for the Levites are more upright of heart to sanctify themselves than the priests.
