Nehemia 12:45

Walifanya ibada ya Mungu wao na ibada ya utakaso, nao waimbaji na walinzi wa lango wakafanya hivyo pia, kufuatana na amri za Daudi na Solomoni mwanawe.

And both the singers and the porters kept the ward of their God, and the ward of the purification, according to the commandment of David, and of Solomon his son.
