Nehemiah 12:44-47 NLT

44 On that day men were appointed to be in charge of the storerooms for the offerings, the first part of the harvest, and the tithes. They were responsible to collect from the fields outside the towns the portions required by the Law for the priests and Levites. For all the people of Judah took joy in the priests and Levites and their work.
45 They performed the service of their God and the service of purification, as commanded by David and his son Solomon, and so did the singers and the gatekeepers.
46 The custom of having choir directors to lead the choirs in hymns of praise and thanksgiving to God began long ago in the days of David and Asaph.
47 So now, in the days of Zerubbabel and of Nehemiah, all Israel brought a daily supply of food for the singers, the gatekeepers, and the Levites. The Levites, in turn, gave a portion of what they received to the priests, the descendants of Aaron.
