'Depths' in the Bible

Flee ye, turn back, dwell in the depths, O inhabitants of Dedan; for I will bring the calamity of Esau upon him, the time that I shall visit him.

Flee ye, wander far off, dwell in the depths, O ye inhabitants of Hazor, saith Jehovah; for Nebuchadrezzar king of Babylon hath taken counsel against you, and hath conceived a purpose against you.
