'Covering' in the Bible

It happened in the six hundred first year, in the first month, the first day of the month, the waters were dried up from the earth. Noah removed the covering of the ship, and looked. He saw that the surface of the ground was dried.

To Sarah he said, "Behold, I have given your brother a thousand pieces of silver. Behold, it is for you a covering of the eyes to all that are with you. In front of all you are vindicated."
