Following are a number of back-translations as well as a sample translation for translators of 2 Chronicles 7:6:

• Kupsabiny: “The priests and Levites stood where it was prepared for (them). The Levites had taken hold of the musical instruments that David had made to praise God with. Those people were singing/dancing saying, ‘His love stays forever.’ The priests blow horns from the other side while all the people of Israel were standing.” (Source: Kupsabiny Back Translation)
• Newari: “The priests and Levites stood in their respective places. Taking instruments that King David had made to give thanks and praise to the LORD, they praised the LORD in this way, "His love endures forever". The priests blew their trumpets before [PROBLEM] the Levites. At that time all the Israelites were standing.” (Source: Newari Back Translation)
• Hiligaynon: “The priests took-their-positions in the temple, and also the Levites who are-singing, ‘His love is without end.’ They play the song with the instruments that King David had-made to praise God. Before/[lit. In front-of] the Levites, the priests also sound their trumpets while all the Israelinhon were standing.” (Source: Hiligaynon Back Translation)
• English: “The priests stood in their positions, and the other descendants of Levi stood in their positions holding the musical instruments to praise Yahweh, instruments that King David had caused to be made for praising Yahweh and thanking him. They sang, ‘He faithfully loves us forever.’ Facing the other descendants of Levi the priests stood, blowing their trumpets, while all the Israeli people were standing and listening.” (Source: Translation for Translators)
