'Deep' in the Bible

Heaving a deep and troubled sigh, He said, "Why do the men of to-day ask for a sign? In solemn truth I tell you that no sign will be given to the men of to-day."

This the High Priests and Scribes heard, and they began to devise means to destroy Him. For they were afraid of Him, because of the deep impression produced on all the people by His teaching.
