'Bearer' in the Bible

His spear shaft was like a weaver’s beam, and the iron point of his spear weighed 15 pounds. In addition, a shield-bearer was walking in front of him.

The Philistine came closer and closer to David, with the shield-bearer in front of him.

when the person told me, ‘Look, Saul is dead,’ he thought he was a bearer of good news, but I seized him and put him to death at Ziklag. That was my reward to him for his news!
