'Touch' in the Bible

And the king said, Whosoever saith ought unto thee, bring him to me, and he shall not touch thee any more.

And the man said unto Joab, Though I should receive a thousand shekels of silver in mine hand, yet would I not put forth mine hand against the king's son: for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom.

But the man that shall touch them must be fenced with iron and the staff of a spear; and they shall be utterly burned with fire in the same place.
