25 And he stationed the Levites in the house of the Lord with cymbals, harps, and lyres, according to the commandment of David and of Gad the king's seer and of Nathan the prophet, for the commandment was from the Lord through his prophets. 26 The Levites stood with the instruments of David, and the priests with the trumpets. 27 Then Hezekiah commanded that the burnt offering be offered on the altar. And when the burnt offering began, the song to the Lord began also, and the trumpets, accompanied by the instruments of David king of Israel. 28 The whole assembly worshiped, and the singers sang, and the trumpeters sounded. All this continued until the burnt offering was finished. 29 When the offering was finished, the king and all who were present with him bowed themselves and worshiped. 30 And Hezekiah the king and the officials commanded the Levites to sing praises to the Lord with the words of David and of Asaph the seer. And they sang praises with gladness, and they bowed down and worshiped.
31 Then Hezekiah said, “You have now consecrated yourselves to the Lord. Come near; bring sacrifices and thank offerings to the house of the Lord.” And the assembly brought sacrifices and thank offerings, and all who were of a willing heart brought burnt offerings. (ESV)
3 The contribution of the king from his own possessions was for the burnt offerings: the burnt offerings of morning and evening, and the burnt offerings for the Sabbaths, the new moons, and the appointed feasts, as it is written in the Law of the Lord. 4 And he commanded the people who lived in Jerusalem to give the portion due to the priests and the Levites, that they might give themselves to the Law of the Lord. 5 As soon as the command was spread abroad, the people of Israel gave in abundance the firstfruits of grain, wine, oil, honey, and of all the produce of the field. And they brought in abundantly the tithe of everything. 6 And the people of Israel and Judah who lived in the cities of Judah also brought in the tithe of cattle and sheep, and the tithe of the dedicated things that had been dedicated to the Lord their God, and laid them in heaps. 7 In the third month they began to pile up the heaps, and finished them in the seventh month. 8 When Hezekiah and the princes came and saw the heaps, they blessed the Lord and his people Israel. 9 And Hezekiah questioned the priests and the Levites about the heaps. 10 Azariah the chief priest, who was of the house of Zadok, answered him, “Since they began to bring the contributions into the house of the Lord, we have eaten and had enough and have plenty left, for the Lord has blessed his people, so that we have this large amount left.”
11 Then Hezekiah commanded them to prepare chambers in the house of the Lord, and they prepared them. 12 And they faithfully brought in the contributions, the tithes, and the dedicated things. The chief officer in charge of them was Conaniah the Levite, with Shimei his brother as second, (ESV)
