2 Samuel 21:19

Then a champion came out from the camps of the Philistines named Goliath, from Gath, whose height was six cubits and a span.

And the shaft of his spear was like a weaver’s beam, and the head of his spear weighed six hundred shekels of iron; his shield-carrier also walked before him.

Then Ishbi-benob, who was among those born to the giants, the weight of whose spear was three hundred shekels of bronze in weight, was girded with a new sword, and he intended to strike down David.

Now it happened afterwards, that war broke out at Gezer with the Philistines; then Sibbecai the Hushathite struck down Sippai, one among those born of the giants, and they were subdued.

And there was war with the Philistines again, and Elhanan the son of Jair struck down Lahmi the brother of Goliath the Gittite, the shaft of whose spear was like a weaver’s beam.
