10 Bible Verses about How To Fast

in order to confirm these days of Purim at their proper time just as Mordecai the Jew and Queen Esther had established them and just as they had committed themselves and their descendants to the practices of fasting and lamentation.

Will the fast I choose be like this:
A day for a person 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 to the Lord?

Isn’t the fast I choose:
To break the chains of wickedness,
to untie the ropes of the yoke,
to set the oppressed free,
and to tear off every yoke?

Yet when they were sick,
my clothing was sackcloth;
I humbled myself with fasting,
and my prayer was genuine.

“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!

But when you fast, put oil on your head, and wash your face,

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.

“Why have we fasted, but You have not seen?
We have denied ourselves, but You haven’t noticed!”
“Look, you do as you please on the day of your fast,
and oppress all your workers.

“Ask all the people of the land and the priests: When you fasted and lamented in the fifth and in the seventh months for these 70 years, did you really fast for Me?

You fast with contention and strife
to strike viciously with your fist.
You cannot fast as you do today,
hoping to make your voice heard on high.
