'Axe' in the Bible

as when he goeth into the wood with his neighbour to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the iron slippeth from the handle, and lighteth upon his neighbour, that he die; such an one shall flee unto one of these cities, and live;

When thou shalt besiege a city many days, in making war against it to take it, thou shalt not destroy the trees thereof by lifting up an axe against them; for thou canst eat of them; and thou shalt not cut them down, for is the tree of the field a man that it should be besieged?
