'Covered' in the Bible

And behold, there arose a great tempest in the sea, insomuch that the boat was covered with the waves: but he was asleep.

Fear them not therefore: for there is nothing covered, that shall not be revealed; and hid, that shall not be known.

But there is nothing covered up, that shall not be revealed; and hid, that shall not be known.

saying , Blessed are they whose iniquities are forgiven, And whose sins are covered.

Every man praying or prophesying, having his head covered, dishonoreth his head.
