Mark 8
11 Ref The Pharisees came out and began to question him, seeking from him a sign from heaven, and testing him.
12 Ref He sighed deeply in his spirit, and said, "Why does this generation{The word translated "generation" here (genea) could also be translated "people," "race," or "family."} seek a sign? Most assuredly I tell you, no sign will be given to this generation."
