'Wielding' in the Bible

"If you besiege a town [for] many days to make war against it [in order to] seize it, you shall not destroy its trees by wielding an ax against them, for you may eat from them, and [so] you must not cut them down. Are the trees of the field humans that they should come in siege {against you}?

Now Abishai the brother of Joab the son of Zeruiah [was] himself the leader of the thirty. He [was] wielding his spear against three hundred slain and {gained a name} among the thirty.

Then Joab gave the number of the counting of the people to the king. Israel [was] eight hundred thousand {valiant warriors} wielding the sword, and the men of Judah [were] five hundred thousand.
