2 Samuel 21:16-19

16And Ishbibenob, who was of the children of Raphah — the weight of his lance was three hundred shekels of bronze, and he was girded with new [armour] — thought to smite David.

17And Abishai the son of Zeruiah succoured him, and smote the Philistine and killed him. Then the men of David swore to him, saying, Thou shalt go no more out with us to battle, that thou quench not the lamp of Israel.

18And it came to pass after this, that there was again a battle with the Philistines, at Gob; then Sibbechai the Hushathite smote Saph, who was of the children of Raphah.

19And there was again a battle at Gob with the Philistines; and Elhanan the son of Jaare-oregim, a Bethlehemite, smote Goliath the Gittite; now the shaft of his spear was like a weaver's beam.
