'Shadowing' in the Bible

Ha! land shadowing with wings, which art beyond the rivers of Cush,

Behold, Assyria was a cedar in Lebanon, with fair branches and a shadowing shroud, and of a high stature: and his top was amidst the thick boughs.

and above over it the cherubim of glory shadowing the mercy-seat; concerning which it is not now the time to speak in detail.
