Luke 11:29

29 As the crowd swelled, he took a fresh tack: "The mood of this age is all wrong. Everybody's looking for proof, but you're looking for the wrong kind. All you're looking for is something to titillate your curiosity, satisfy your lust for miracles. But the only proof you're going to get is the Jonah-proof given to the Ninevites, which looks like no proof at all.

Luke 11:29 Meaning and Commentary

Luke 11:29

And when the people were gathered thick together
Upon this woman's lifting up her voice, and saying the things she did; or rather to see what sign he would give, which some had desired ( Luke 11:16 )

he began to say, this is an evil generation.
The Alexandrian copy, two copies of Beza's, and the Vulgate Latin, and Arabic versions read, "this generation is an evil generation"; and also it was an "adulterous one", as is added in ( Matthew 12:39 )

they seek a sign;
for they had asked one of him, ( Luke 11:16 )

and there shall no sign be given it, but the sign of Jonas the
prophet; one like unto it: (See Gill on Matthew 12:39)

Luke 11:29 In-Context

27 While he was saying these things, some woman lifted her voice above the murmur of the crowd: "Blessed the womb that carried you, and the breasts at which you nursed!"

28 Jesus commented, "Even more blessed are those who hear God's Word and guard it with their lives!"

29 As the crowd swelled, he took a fresh tack: "The mood of this age is all wrong. Everybody's looking for proof, but you're looking for the wrong kind. All you're looking for is something to titillate your curiosity, satisfy your lust for miracles. But the only proof you're going to get is the Jonah-proof given to the Ninevites, which looks like no proof at all.

30 What Jonah was to Nineveh, the Son of Man is to this age.

31 "On Judgment Day the Ninevites will stand up and give evidence that will condemn this generation, because when Jonah preached to them they changed their lives. A far greater preacher than Jonah is here, and you squabble about 'proofs.'
