2 Chr 7:6

וְהַכֹּהֲנִ֞ים עַל־מִשְׁמְרוֹתָ֣ם עֹמְדִ֗ים וְהַלְוִיִּ֞ם בִּכְלֵי־שִׁ֤יר יְהוָה֙ אֲשֶׁ֨ר עָשָׂ֜ה דָּוִ֣יד הַמֶּ֗לֶךְ לְהֹד֤וֹת לַיהוָה֙ כִּֽי־לְעוֹלָ֣ם חַסְדּ֔וֹ בְּהַלֵּ֥ל דָּוִ֖יד בְּיָדָ֑ם וְהַכֹּהֲנִים֙ מחצצרים מַחְצְרִ֣ים נֶגְדָּ֔ם וְכָל־יִשְׂרָאֵ֖ל עֹמְדִֽים׃ ס

The priests stood at their posts, as did the Levites with the musical instruments of the LORD, which King David had made for giving thanks to the LORD and with which David had offered praise, saying, “For His loving devotion endures forever.” Across from the Levites, the priests sounded trumpets, and all the Israelites were standing.
