29 G1161 And G1865 when G3793 the multitudes G1865 were gathering together G756 unto him, he began G3004 to say, G3778 This G1074 generation G2076 is G1074 an G4190 evil G1074 generation: G4592 it seeketh after a sign; G2532 and G1325 there shall G3756 no G4592 sign G1325 be given G1487 to it G3361 but G4592 the sign G2495 of Jonah.

30 G1063 For G2531 even as G2495 Jonah G1096 became G4592 a sign G3536 unto the Ninevites, G3779 so G2071 shall G2532 also G5207 the Son G444 of man G2071 be G1074 to G3778 this G1074 generation.
