Matthew 6

Fasting, The True Treasure, Wealth (Mammon)

16 "And whenever you are fasting, do not look gloomy like the hypocrites, for they put on a sad and dismal face [like actors, discoloring their faces with ashes or dirt] so that their fasting may be seen by men. I assure you and most solemnly say to you, they [already] have their reward in full. [Is 58:5]
