1 Mambo Ya Nyakati 11:6

Daudi alikuwa amesema, “Yeyote aongozaye mashambulizi dhidi ya Wayebusi, atakuwa jemadari mkuu.” Yoabu mwana wa Seruya akawa wa kwanza kukwea, naye akawa mkuu.

And David said, Whosoever smiteth the Jebusites first shall be chief and captain. So Joab the son of Zeruiah went first up, and was chief.
