what does the bible say?
In Old Testament times, the role of an armor-bearer was one of honor in which a specific servant carried weapons for his commander. Military leaders such as Abimelech (Judges 9:54), King Saul (1 Samuel 16:21, 31:4), Jonathan (1 Samuel 14:6-17), and Joab (2 Samuel 18:15) all used armor-bearers, and the warrior Goliath had a shield-bearer (1 Samuel 17:7). Aside from David, the only armor-bearer mentioned by name is Naharai of Beeroth, Joab’s armor-bearer (2 Samuel 23:37; 1 Chronicles 11:39), who was also a mighty warrior in Israel’s army. The modern church use of armor-bearers is much different. Some churches use the term “armor-bearer” to designate a position in which a person will physically carry the Bible, symbolically representing “the sword of the Spirit” (Ephesians 6:17) and serve the pastor of the church in other capacities. The goal of someone in this position is often to take on the more minor tasks for a pastor or elder so that he can prioritize fulfilling his ultimate ministry in the church (Acts 6:1-7).
