'Depths' in the Bible

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

Flee, wander far off, dwell in the depths, you inhabitants of Hazor, says Yahweh; for Nebuchadnezzar king of Babylon has taken counsel against you, and has conceived a purpose against you.
