16And Ishbi-benob, one of the descendants aof the giants, whose spear weighed three hundred shekels
A  shekel was about 2/5 ounce or 11 grams
of bronze, and who was armed with a new sword, thought to kill David.
17But Abishai the son of Zeruiah came to his aid and attacked the Philistine and killed him. Then David’s men swore to him, c“You shall no longer go out with us to battle, lest you quench dthe lamp of Israel.”
