'Covers' in the Bible

“The earth is given into the hands of the wicked;He covers the faces of its judges [so that they are blind to justice].If it is not He, then who is it [that is responsible for all this injustice]?

Or darkness, so that you cannot see,And a flood of water covers you.

“He covers the face of the full moonAnd spreads His cloud over it.

“Behold, He spreads His lightning around Him [against the dark clouds],And He covers the depths of the sea.

“He covers His hands with the lightning,And commands it to strike the mark.
