Mark 2:18-20 New Revised Standard Version (NRSV)
The Question about Fasting
18 Now John’s disciples and the Pharisees were fasting; and people[a] came and said to him, “Why do John’s disciples and the disciples of the Pharisees fast, but your disciples do not fast?” 19 Jesus said to them, “The wedding guests cannot fast while the bridegroom is with them, can they? As long as they have the bridegroom with them, they cannot fast. 20 The days will come when the bridegroom is taken away from them, and then they will fast on that day.
