'Crouching' in the Bible

And I have given Rabbah for a habitation of camels, And the sons of Ammon for the crouching of a flock, And ye have known that I am Jehovah.

Speak, and thou hast said: Thus said the Lord Jehovah: Lo, I am against thee, Pharaoh king of Egypt! The great dragon that is crouching in the midst of his floods, Who hath said, My flood is my own, And I -- I have made it for myself.
