'Touching' in the Bible

Now will I sing to my wellbeloved a song of my beloved touching his vineyard. My wellbeloved hath a vineyard in a very fruitful hill:

And after touching my mouth with it, he said, See, your lips have been touched with this; and your evil is taken away, and you are made clean from sin.

He pursues them, going on safely,hardly touching the path with his feet.

Away! away! go out from there, touching no unclean thing; go out from among her; be clean, you who take up the vessels of the Lord.
