Luke 11:32

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

30 For as Jonas was a sign unto the Ninevites, so shall also 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 Nineve shall rise up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonas; and, behold, a greater than Jonas [is] here.

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

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

35 Take heed therefore that the light which is in thee be not darkness.
