Mark 8:11-13 - Pharisees Demand A Sign
11 And the Pharisees came out, and began to discuss with Him, seeking from Him a sign from heaven, tempting Him. 12 And, sighing deeply in His spirit, He saith, "Why does this generation seek a sign? verily I say to you, there shall no sign be given to this generation." 13 And, leaving them, He again embarked, and departed to the other side.
