11. The Pharisees came and began to argue with and question Him, demanding from Him a sign (an attesting miracle from heaven) [maliciously] to test Him.
12. And He groaned and sighed deeply in His spirit and said, Why does this generation demand a sign? Positively I say to you, no sign shall be given this generation.
13. And He went away and left them and, getting into the boat again, He departed to the other side.
14. Now they had [completely] forgotten to bring bread, and they had only one loaf with them in the boat.
15. And Jesus [repeatedly and expressly] charged and admonished them, saying, Look out; keep on your guard and beware of the leaven of the Pharisees and the leaven of Herod and the Herodians.
