'Used' in the Bible

and a dead body's fat or mangled carcass's fat may be used for any {purpose}, but you certainly must not eat it.

And he shall examine the infection on the seventh day; if the infection has spread on the garment or on the woven material or on the fabric or on the leather, for any work for which the leather is used, the infection [is] a destructive skin disease--it [is] unclean.
