1 Chronicles 11:6

Whosoever smiteth the Jebusites first shall be chief and captain The Chronicler has simplified the very difficult phrase which occurs in the parallel passage (2 Samuel 5:8).

Joab the son of Zeruiah Zeruiah was David's sister (1 Chronicles 2:16). It is not said in Samuel that Joab first became commander-in-chief on this occasion; on the contrary he appears in command (2 Samuel 2:13) during the civil war against the house of Saul. Perhaps he was first formally acknowledged as commander at the capture of Jebus.
