'Deep' in the Bible

For Yahweh has poured out on you a spirit of deep sleep, and has closed your eyes, the prophets; and he has covered your heads, the seers.

For his burning place has long been ready. Yes, for the king it is prepared. He has made its pyre deep and large with fire and much wood. Yahweh's breath, like a stream of sulfur, kindles it.

You will no longer see the fierce people, a people of a deep speech that you can't comprehend, with a strange language that you can't understand.

who says to the deep, 'Be dry,' and 'I will dry up your rivers;'

Isn't it you who dried up the sea, the waters of the great deep; who made the depths of the sea a way for the redeemed to pass over?
