Bible verses about fasting

When you fast, do not be somber like the hypocrites, for they disfigure their faces to show men they are fasting. Truly I tell you, they already have their full reward. But when you fast, anoint your head and wash your face, so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.

You fast with contention and strife to strike viciously with your fist. You cannot fast as you do today and have your voice be heard on high. Is this the fast I have chosen: a day for a man to deny himself, to bow his head like a reed, and to spread out sackcloth and ashes? Will you call this a fast and a day acceptable…
