17 But when you go without food, put oil on your head and make your face clean; 18 So that no one may see that you are going without food, but your Father in secret; and your Father, who sees in secret, will give you your reward.

Matthew Henry's Commentary on Matthew 6:17-18

Commentary on Matthew 6:16-18

(Read Matthew 6:16-18)

Religious fasting is a duty required of the disciples of Christ, but it is not so much a duty itself, as a means to dispose us for other duties. Fasting is the humbling of the soul, Psalm 35:13; that is the inside of the duty; let that, therefore, be thy principal care, and as to the outside of it, covet not to let it be seen. God sees in secret, and will reward openly.
