'Fasting' in the Bible

“Whenever you fast, do not put on a gloomy face as the hypocrites do, for they neglect their appearance so that they will be noticed by men when they are fasting. Truly I say to you, they have their reward in full.

so that your fasting will not be noticed by men, but by your Father who is in secret; and your Father who sees what is done in secret will reward you.

[But this kind does not go out except by prayer and fasting.”]

John’s disciples and the Pharisees were fasting; and they *came and *said to Him, “Why do John’s disciples and the disciples of the Pharisees fast, but Your disciples do not fast?”

While they were ministering to the Lord and fasting, the Holy Spirit said, “Set apart for Me Barnabas and Saul for the work to which I have called them.”

When they had appointed elders for them in every church, having prayed with fasting, they commended them to the Lord in whom they had believed.
