Mattityahu 12:37-39

Orthodox Jewish Bible

³⁷ For by your dvarim you will be pronounced tzodek (righteous), and by your dvarim you will be charged with guilt.

³⁸ Then some of the Sofrim and Perushim answered Rebbe, Melech HaMoshiach, saying, Rabbi, we desire to see an ot (miraculous sign) from you.

³⁹ But Rebbe, Melech HaMoshiach answered them, Dor rah umnaef (an evil and adulterous generation) seeks for an ot (miraculous sign), but no ot will be given it except the ot of Yonah HaNavi.
