'Touched' in the Bible

And flesh touched by any unclean thing may not be taken for food: it is to be burned with fire; and as for the flesh of the peace-offerings, everyone who is clean may take it as food:

Their flesh may not be used for food, and their dead bodies may not even be touched; they are unclean to you.

And she will be unclean for thirty-three days till the flow of her blood is stopped; no holy thing may be touched by her, and she may not come into the holy place, till the days for making her clean are ended.

And any vessel of earth which has been touched by the unclean man will have to be broken and any vessel of wood washed.
