Whenever you fast, do not assume a gloomy expression like the hypocrites who contort their faces so that others may realize that they are fasting. Amen, I say to you, they have received their reward.
But when you fast, put oil on your head and wash your face, so that the fact that you are fasting will not be obvious to others but only to your Father who is hidden. And your Father who sees everything that is done in secret will reward you.
On one occasion, while they were worshiping the Lord and fasting, the Holy Spirit said, “Set Barnabas and Saul apart for me to do the work to which I have called them.”
This rather is the type of fast that I wish: to loosen the fetters of injustice, to undo the thongs of the yoke, to set free those who are oppressed and to break every yoke.
Do not deprive one another, except perhaps by mutual consent for a specified time so as to devote yourselves to prayer. Then come together again so that Satan may not tempt you by taking advantage of your lack of self-control.
Filled with the Holy Spirit, Jesus returned from the Jordan and was led by the Spirit into the desert for forty days, where he was tempted by the devil. During that time he ate nothing, and at the end of it he was famished.
Moses remained with the Lord for forty days and forty nights without eating bread or drinking water. And he wrote the words of the covenant, the Ten Commandments, on the tablets.
Go, and assemble all the Jews who are in Susa, and fast for me. Do not eat or drink for three days, night or day. My maids and I will do the same thing. After that, I will go to the king—against the law. And if I perish, I perish!
For I know full well the plans I have for you, plans for your welfare and not for your misfortune, plans that will offer you a future filled with hope.
