And at the dedication of the wall of Jerusalem they sought the Levites in all their places, to bring them to Jerusalem to celebrate the dedication with gladness, with thanksgivings and with singing, with cymbals, harps, and lyres.

...

Thus I cleansed them from everything foreign, and I established the duties of the priests and Levites, each in his work; and I provided for the wood offering at appointed times, and for the firstfruits.

Remember me, O my God, for good.

(Nehemiah 12.27, 13.30-31)
