45 And David saith unto the Philistine, 'Thou art coming unto me with sword, and with spear, and with buckler, and I am coming unto thee in the name of Jehovah of Hosts, God of the ranks of Israel, which thou hast reproached.

Matthew Henry's Commentary on 1 Samuel 17:45

Commentary on 1 Samuel 17:40-47

(Read 1 Samuel 17:40-47)
