Daniel 4:3

“And in the days of those kings the God of heaven will cause a kingdom to rise up which will never be destroyed, and that kingdom will not be left for another people; it will crush and put an end to all these kingdoms, but it will itself stand forever.

“But at the end of those days, I, Nebuchadnezzar, lifted up my eyes toward heaven, and my knowledge returned to me, and I blessed the Most High and praised and honored Him who lives forever; For His dominion is an everlasting dominion, And His kingdom endures from generation to generation.

“I make a decree that in all the dominion of my kingdom, men are to fear and be in dread before the God of Daniel; For He is the living God and enduring forever, And His kingdom is one which will not be destroyed, And His dominion will be unto the end.

“He saves and delivers and does signs and wonders In heaven and on earth, Who has also saved Daniel from the power of the lions.”

So Jesus said to him, “Unless you people see signs and wonders, you will never believe.”
