'Cover' in the Bible

And some began to spit on him, and to cover his face, and to buffet him, and to say unto him, Prophesy: and the officers received him with blows of their hands.

Then shall they begin to say to the mountains, Fall on us; and to the hills, Cover us.

let him know, that he who converteth a sinner from the error of his way shall save a soul from death, and shall cover a multitude of sins.
