'Fasting' in the Bible

“Whenever you fast, don’t be sad-faced like the hypocrites. For they make their faces unattractive so their fasting is obvious to people. I assure you: They’ve got their reward!

so that you don’t show your fasting to people but to your Father who is in secret. And your Father who sees in secret will reward you.

[However, this kind does not come out except by prayer and fasting.]”

Now John’s disciples and the Pharisees were fasting. People came and asked Him, “Why do John’s disciples and the Pharisees’ disciples fast, but Your disciples do not fast?”

And He told them, “This kind can come out by nothing but prayer [and fasting].”

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

When they had appointed elders in every church and prayed with fasting, they committed them to the Lord in whom they had believed.
