'Deep' in the Bible

When He had finished speaking, He said to Simon, “Put out into deep water and let down your nets for a catch.”

He is like a man building a house, who dug deep and laid the foundation on the rock. When the flood came, the river crashed against that house and couldn’t shake it, because it was well built.

Peter and those with him were in a deep sleep, and when they became fully awake, they saw His glory and the two men who were standing with Him.
