Rashi
And...his catapult [Heb. וּמְחִי קָבָלוֹ.] This is one of the devices of the siege, to throw huge rocks and to strike opposite it, e la hone de sa pereyre in Old French, and the striking of his stone-throwing machine. Others render קָבָלוֹ as desarbalete in Old French, of his war-machines.
Rashi
with his instruments of destruction [Heb. בְּחַרְבּוֹתָיו,] with tools of destruction that he will bring with him.
