2 Samuel 21:18 (KJV)

And Ishbi–benob, which was of the sons of the giant, the weight of whose spear weighed three hundred shekels of brass in weight, he being girded with a new sword, thought to have slain David.

But Abishai the son of Zeruiah succoured 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 light of Israel.

And it came to pass after this, that there was again a battle with the Philistines at Gob: then Sibbechai the Hushathite slew Saph, which was of the sons of the giant.

And there was again a battle in Gob with the Philistines, where Elhanan the son of Jaare–oregim, a Beth–lehemite, slew the brother of Goliath the Gittite, the staff of whose spear was like a weaver’s beam.

And there was yet a battle in Gath, where was a man of great stature, that had on every hand six fingers, and on every foot six toes, four and twenty in number; and he also was born to the giant.
