2 Chronicles 29:25–34

²⁵And he set the Levites in the house of Jehovah with cymbals, with lutes, and with harps, according to the commandment of David, and of Gad the king’s seer, and of Nathan the prophet; for the commandment was of Jehovah through his prophets. ²⁶And the Levites stood with the instruments of David, and the priests with the trumpets. ²⁷And Hezekiah commanded to offer up the burnt-offering on the altar. And at the moment the burnt-offering began, the song of Jehovah began, and the trumpets, accompanied by the instruments of David king of Israel. ²⁸And all the congregation worshipped, and the singers sang, and the trumpeters sounded, all the time until the burnt-offering was finished. ²⁹And when they had ended offering the burnt-offering, the king and all that were present with him bowed themselves and worshipped. ³⁰And king Hezekiah and the princes commanded the Levites to sing praise to Jehovah with the words of David, and of Asaph the seer. And they sang praises with gladness, and bowed their heads and worshipped. ³¹And Hezekiah answered and said, Now ye have consecrated yourselves to Jehovah, come near and bring sacrifices and thank-offerings into the house of the Lord. And the congregation brought in sacrifices and thank-offerings; and as many as were of a willing heart, burnt-offerings. ³²And the number of the burnt-offerings, which the congregation brought, was seventy bullocks, a hundred rams, two hundred lambs: all these were for a burnt-offering to Jehovah. ³³And the consecrated things were six hundred oxen and three thousand sheep. ³⁴Only the priests were too few, and they could not flay all the burnt-offerings; therefore their brethren the Levites helped them, until the work was ended, and until the priests had hallowed themselves; for the Levites were more upright in heart to hallow themselves than the priests.
