'Tool' in the Bible

{For example}, when somebody goes with his neighbor into the forest to cut wood, and the iron [head] slips from the handle [of the tool] and strikes his neighbor and he dies, [then] he may flee to one of these cities, and [so] he may live.

You must have a digging tool in your equipment; when you relieve yourself, dig a hole with it and cover up your excrement.

And there shalt thou build an altar unto the LORD thy God, an altar of stones: thou shalt not lift up any iron tool upon them.
