Mattityahu (Mat) 9:14-15

Next, Yochanan’s talmidim came to him and asked, “Why is it that we and the P’rushim fast frequently, but your talmidim don’t fast at all?” Yeshua said to them, “Can wedding guests mourn while the bridegroom is still with them? But the time will come when the bridegroom is taken away from them; then they will fast.
