2 Mambo ya Nyakati 35 : 15 2nd Chronicles chapter 35 verse 15

Nao waimbaji, wana wa Asafu wakasimama mahali pao, kama alivyoamuru Daudi, na Asafu, na Hemani, na Yeduthuni mwonaji wa mfalme; nao mabawabu walikuwa katika kila lango; hawakuhitaji kuondoka katika huduma yao, kwa kuwa ndugu zao Walawi wakawaandalia.

The singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the porters were at every gate: they didn't need to depart from their service; for their brothers the Levites prepared for them.
