Matthew 23:13; Matthew 23:15

13 "But woe to you hypocritical Torah-teachers and P'rushim! For you are shutting the Kingdom of Heaven in people's faces, neither entering yourselves nor allowing those who wish to enter to do so.

15 "Woe to you hypocritical Torah-teachers and P'rushim! You go about over land and sea to make one proselyte; and when you succeed, you make him twice as fit for Gei-Hinnom as you are!
