Commentary for II Chronicles 23:18

וַיָּשֶׂם֩ יְהוֹיָדָ֨ע פְּקֻדֹּ֜ת בֵּ֣ית יְהוָ֗ה בְּיַ֨ד הַכֹּהֲנִ֣ים הַלְוִיִּם֮ אֲשֶׁ֣ר חָלַ֣ק דָּוִיד֮ עַל־בֵּ֣ית יְהוָה֒ לְֽהַעֲל֞וֹת עֹל֣וֹת יְהוָ֗ה כַּכָּת֛וּב בְּתוֹרַ֥ת מֹשֶׁ֖ה בְּשִׂמְחָ֣ה וּבְשִׁ֑יר עַ֖ל יְדֵ֥י דָוִֽיד׃

And Jehoiada appointed the offices of the house of the LORD under the hand of the priests the Levites, whom David had distributed in the house of the LORD, to offer the burnt-offerings of the LORD, as it is written in the Law of Moses, with rejoicing and with singing, according to the direction of David.
