Luke 11:31

28 But he said, Yes, rather blessed [are] they that hear the word of God, and keep it.

29 And when the people were assembled in crowds, he began to say, This is an evil generation: they seek a sign; and there shall no sign be given to it, but the sign of Jonah the prophet.

30 For as Jonah was a sign to the Ninevites, so also shall the Son of man be to this generation.

31 The queen of the south shall rise up in the judgment with the men of this generation, and condemn them: for she came from the utmost parts of the earth, to hear the wisdom of Solomon; and behold, a greater than Solomon [is] here.

32 The men of Nineveh shall rise up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonah; and behold, a greater than Jonah [is] here.

33 No man when he hath lighted a candle, putteth [it] in a secret place, neither under a close vessel, but on a candlestick, that they who come in may see the light.

34 The light of the body is the eye: therefore when thy eye is single, thy whole body also is full of light; but when [thy eye] is evil, thy body also [is] full of darkness.
