2 Samuel 21:16

And Ishbibenob, which [was] of the sons of the giant
Of Goliath, or of a giant, of the race of them:

the weight of whose spear [weighed] three hundred [shekels] of brass in
weight;
which must be understood either of the wood of it, or of the head of it, the flaming point of it, as many interpret it; and if so, it was but half the weight of Goliath's spear, unless there was any difference of the weight of iron and of brass, see ( 1 Samuel 17:7 ) ;

he being girded with a new [sword];
or rather with a new girdle, as the Targum; and so Jarchi, which might be given him as a mark of honour, or as a token of his having a commission in the army:

thought to have slain David;
his aim was at him, and perceiving him faint and feeble, thought to take the advantage of it, and dispatch him.
