'Bearer' in the Bible

The shaft of his spear was like a weaver's beam, and the iron point of his spear weighed six hundred shekels. His shield bearer was walking before him.

The Philistine kept coming closer to David, with his shield bearer walking in front of him.

But Joab said to him, "You will not be a bearer of good news today. You will bear good news some other day, but not today, for the king's son is dead."
