2 Chronicles 30:22-24

Young's Literal Translation

²² And Hezekiah speaketh unto the heart of all the Levites, those giving good understanding concerning Jehovah, and they eat the appointed thing seven days; sacrificing sacrifices of peace-offerings, and making confession to Jehovah, God of their fathers.

²³ And all the assembly take counsel to keep other seven days, and they keep seven days [with] joy;

²⁴ for Hezekiah king of Judah hath presented to the assembly a thousand bullocks, and seven thousand sheep; and the heads have presented to the assembly bullocks a thousand, and sheep ten thousand; and priests sanctify themselves in abundance.
