Mark 8:11-13
Mark 8:11-13 NKJV
Then the Pharisees came out and began to dispute with Him, seeking from Him a sign from heaven, testing Him. But He sighed deeply in His spirit, and said, “Why does this generation seek a sign? Assuredly, I say to you, no sign shall be given to this generation.” And He left them, and getting into the boat again, departed to the other side.
