Matthew 6:16-18

16“And whenever you fast, do not become sad-faced like the hypocrites, for they neglect their faces to make their fasting evident to men. Amen, I tell you, they have their reward in full!

17But when you fast, anoint your head and wash your face,

18so that your fasting won’t be evident to men, but to your Father who is in secret. And your Father, who sees in secret, will reward you.
