2 Samuel 21:16-19 American Standard Version (ASV)

16. and Ishbibenob, who was of the sons of the giant, the weight of whose spear was three hundred shekels of brass in weight, he being girded with a new sword, thought to have slain David.

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

18. And it came to pass after this, that there was again war with the Philistines at Gob: then Sibbecai the Hushathite slew Saph, who was of the sons of the giant.

19. And there was again war with the Philistines at Gob; and Elhanan the son of Jaareoregim the Beth-lehemite slew Goliath the Gittite, the staff of whose spear was like a weaver’s beam.
