Chapter XV.—In what the true fasting consists.

“Learn, therefore, to keep the true fast of God, as Isaiah says, that you may please God. Isaiah has cried thus: ‘Shout vehemently, and do not spare: lift up thy voice as with a trumpet, and show My people their transgressions, and the house of Jacob their sins. They seek Me from day to day, and desire to know My ways, as a nation that did righteousness, and forsook not the judgment of God. They ask of Me now righteous judgment, and desire to draw near to God, saying, Wherefore have we fasted, and Thou seest not? and afflicted our souls, and Thou hast not known? Because in the days of your fasting you find your own pleasure, and oppress all those who are subject to you. Behold, ye fast for strifes and debates, and smite the humble with your fists. Why do ye fast for Me, as to-day, so that your voice is heard aloud? This is not the fast which I have chosen, the day in which a man shall afflict his soul. And not even if you bend your neck like a ring, or clothe yourself in sackcloth and ashes, shall you call this a fast, and a day acceptable to the Lord. This is not the fast which I have chosen, saith the Lord; but loose every unrighteous bond, dissolve the terms of wrongous covenants, let the oppressed go free, and avoid every iniquitous contract. Deal thy bread to the hungry, and lead the homeless poor under thy dwelling; if thou seest the naked, clothe him; and do not hide thyself from thine own flesh. Then shall thy light break forth as the morning, and thy garments^19801980    ἱμάτια; some read ἰάματα, as in LXX., “thy health,” the better reading probably. shall rise up quickly: and thy righteousness shall go before thee, and the glory of God shall envelope thee. Then shalt thou cry, and the Lord shall hear thee: while thou art speaking, He will say, Behold, I am here. And if thou take away from thee the yoke, and the stretching out of the hand, and the word of murmuring; and shalt give heartily thy bread to the hungry, and shalt satisfy the afflicted soul; then shall thy light arise in the darkness, and thy darkness shall be as the noon-day: and thy God shall be with thee continually, and thou shalt be satisfied according as thy soul desireth, and thy bones shall become fat, and shall be as a watered garden, and as a fountain of water, or as a land where water fails not.’^19811981    Isa. lviii. 1–12. ‘Circumcise, therefore, the foreskin of your heart,’ as the words of God in all these passages demand.”
