'Sink' in the Bible

He made the sky sink as he descended; a thick cloud was under his feet.

I sink into the deep mire where there is no solid ground; I am in deep water, and the current overpowers me.

Rescue me from the mud! Don't let me sink! Deliver me from those who hate me, from the deep water!

O Lord, make the sky sink and come down! Touch the mountains and make them smolder!
