דברי הימים א, פרק י״א, פסוק ל״ט

Among the elite warriors recognized for their bravery and service, specific individuals held vital roles on the battlefield that required deep trust. There is a consensus among commentators that the role of armor-bearer belonged specifically to Naharai, rather than to Zelek. In this position, Naharai was responsible for carrying the weapons and military equipment of Joab, the son of Zeruiah. He functioned essentially as Joab's close, personal assistant. Furthermore, his background is noted, indicating that he originally came from the city of Beeroth.
