Commentary for II Chronicles 31:2

וַיַּעֲמֵ֣ד יְחִזְקִיָּ֡הוּ אֶת־מַחְלְק֣וֹת הַכֹּהֲנִ֣ים וְ֠הַלְוִיִּם עַֽל־מַחְלְקוֹתָ֞ם אִ֣ישׁ ׀ כְּפִ֣י עֲבֹדָת֗וֹ לַכֹּהֲנִים֙ וְלַלְוִיִּ֔ם לְעֹלָ֖ה וְלִשְׁלָמִ֑ים לְשָׁרֵת֙ וּלְהֹד֣וֹת וּלְהַלֵּ֔ל בְּשַׁעֲרֵ֖י מַחֲנ֥וֹת יְהוָֽה׃ (ס)

And Hezekiah appointed the courses of the priest and the Levites after their courses, every man according to his service, both the priests and the Levites, for burnt-offerings and for peace-offerings, to minister, and to give thanks, and to praise in the gates of the camp of the LORD.
