LXX2012(i)
25 And he stationed the Levites in the house of the Lord with cymbals, and lutes, and harps, according to the commandment of king David, and of Gad the king's seer, and Nathan the prophet: for by the commandment of the Lord the order [was] in the hand of the prophets.
26 And the Levites stood with the instruments of David, and the priests with the trumpets.
27 And Ezekias told [them] to offer up the whole burnt offering on the altar: and when they began to offer the whole burnt offering, they began to sing to the Lord, and the trumpets [accompanied] the instruments of David king of Israel.
28 And all the congregation worshipped, and the psalm-singers [were] singing, and the trumpets sounding, until the whole burnt sacrifice had been completely offered.
29 And when they had done offering [it], the king and all that were present bowed, and worshipped.
30 And king Ezekias and the princes told the Levites to sing hymns to the Lord in the words of David, and of Asaph the prophet: and they sang hymns with gladness, and fell down and worshipped.
