'Fears' in the Bible

Who among you fears the Lord,listening to the voice of His Servant?Who among you walks in darkness,and has no light?Let him trust in the name of Yahweh;let him lean on his God.

I also will choose their delusions, and will bring their fears upon them; because when I called, none did answer; when I spake, they did not hear: but they did evil before mine eyes, and chose that in which I delighted not.
