For in the days of David and Asaph of old there were chief of the singers, and songs of praise and thanksgiving unto God.(Nehemiah 12:46)

And all Israel in the days of Zerubbabel, and in the days of Nehemiah, gave the portions of the singers and the porters, every day his portion: and they sanctified holy things unto the Levites; and the Levites sanctified them unto the children of Aaron.(Nehemiah 12:47)

On that day they read in the book of Moses in the audience of the people; and therein was found written, that the Ammonite and the Moabite should not come into the congregation of God for ever;(Nehemiah 13:1)

Now it came to pass, when they had heard the law, that they separated from Israel all the mixed multitude.(Nehemiah 13:3)

And before this, Eliashib the priest, having the oversight of the chamber of the house of our God, was allied unto Tobiah:(Nehemiah 13:4)

And he had prepared for him a great chamber, where aforetime they laid the meat offerings, the frankincense, and the vessels, and the tithes of the corn, the new wine, and the oil, which was commanded to be given to the Levites, and the singers, and the porters; and the offerings of the priests.(Nehemiah 13:5)
