Jeremiah 33:1-3
Moreover the word of the LORD came unto Jeremiah the second time, while he was yet shut up in the court of the prison, saying, Thus saith the LORD the maker thereof, the LORD that formed it, to establish it; the LORD is his name; Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.
