'Touch' in the Bible

and Zipporah taketh a flint, and cutteth off the foreskin of her son, and causeth it to touch his feet, and saith, 'Surely a bridegroom of blood art thou to me;'

So the Lord says, By this you may be certain that I am the Lord; see, by the touch of this rod in my hand the waters of the Nile will be turned to blood;

And they did so; and Aaron, stretching out the rod in his hand, gave a touch to the dust of the earth, and insects came on man and on beast; all the dust of the earth was changed into insects through all the land of Egypt.

You shall take a bunch of hyssop, dip it in the blood which is in the basin, and touch some of the blood to the lintel [above the doorway] and to the two doorposts; and none of you shall go outside the door of his house until morning.

And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death:

There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount.

And if you make me an altar of stone do not make it of cut stones: for the touch of an instrument will make it unclean.
