16 “And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others.

And your Father who sees in secret will reward you.

Colossians 3:2 ESV
2 Set your minds on things that are above, not on things that are on earth.
Isaiah 58:3-7 ESV
‘Why have we fasted, and you see it not?
Why have we humbled ourselves, and you take no knowledge of it?’
Behold, in the day of your fast you seek your own pleasure,
and oppress all your workers.
4 Behold, you fast only to quarrel and to fight
and to hit with a wicked fist.
Fasting like yours this day
will not make your voice to be heard on high.
5 Is such the fast that I choose,
a day for a person to humble himself?
Is it to bow down his head like a reed,
and to spread sackcloth and ashes under him?
Will you call this a fast,
and a day acceptable to the Lord? (going through the motions)
6 “Is not this the fast that I choose:
to loose the bonds of wickedness,
to undo the straps of the yoke,
to let the oppressed go free,
and to break every yoke?
7 Is it not to share your bread with the hungry
and bring the homeless poor into your house;
when you see the naked, to cover him,
and not to hide yourself from your own flesh?
Isaiah 58:8-10 ESV
Then shall your light break forth like the dawn,
and your healing shall spring up speedily;
your righteousness shall go before you;
the glory of the Lord shall be your rear guard.
9 Then you shall call, and the Lord will answer;
you shall cry, and he will say, ‘Here I am.’
If you take away the yoke from your midst,
the pointing of the finger, and speaking wickedness,
10 if you pour yourself out for the hungry
and satisfy the desire of the afflicted,
then shall your light rise in the darkness
and your gloom be as the noonday.
Nehemiah 1:4-7 ESV
4 As soon as I heard these words I sat down and wept and mourned for days, and I continued fasting and praying before the God of heaven. 5 And I said, “O Lord God of heaven, the great and awesome God who keeps covenant and steadfast love with those who love him and keep his commandments, 6 let your ear be attentive and your eyes open, to hear the prayer of your servant that I now pray before you day and night for the people of Israel your servants, confessing the sins of the people of Israel, which we have sinned against you. Even I and my father's house have sinned. 7 We have acted very corruptly against you and have not kept the commandments, the statutes, and the rules that you commanded your servant Moses.
