'Ax' 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}?

So Abimelech went up Mount Zalmon, he and all his army that [were] with him, and Abimelech took the ax in his hand and cut down a bundle of brushwood, and he lifted it and put [it] on his shoulder. And he said to the army that [was] with him, "What you have seen me do, quickly do also."

It happened as the one [was] felling the log, that the iron ax fell into the water. He called out and said, "Oh, no! My master, it was borrowed!"

Then the man of God said, "Where did it fall?" So he showed him the place, and then he cut off a stick and threw [it] there and made the iron ax float.

If the ax is blunt but one does not sharpen its edge, {he must exert more effort}, but the advantage of wisdom [is] it brings success.

Does the ax boast against the one who cuts with it, or the saw magnify itself against [the] one who moves it to and fro? {As if a rod should move the one who lifts it}! {As if a staff should lift up that which is not wood}!

Already now the ax is positioned at the root of the trees; therefore every tree not producing good fruit is cut down and thrown into the fire.

And even now the ax is positioned at the root of the trees; therefore every tree not producing good fruit is cut down and thrown into the fire."
