'Off' in the Bible

And if any people will not take you in, when you go away from that town, put off its dust from your feet for a witness against them.

Even the dust of your town, which is on our feet, we put off as a witness against you; but be certain of this, that the kingdom of God is near.

Or what king, going to war with another king, will not first take thought if he will be strong enough, with ten thousand men, to keep off him who comes against him with twenty thousand?

And one of them gave a blow to the servant of the high priest, cutting off his right ear.
