'Eye' in the Bible

My mind reels, horror overwhelms me;The twilight I longed for has been turned into fear and trembling for me.

Listen! Your watchmen lift up their voices,Together they shout for joy;For they will see face to faceThe return of the Lord to Zion.

For from days of old no one has heard, nor has ear perceived,Nor has the eye seen a God besides You,Who works and acts in behalf of the one who [gladly] waits for Him.
