Isaiah 1:16-20

16Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil; 17learn to do well; seek justice, relieve the oppressed, judge the fatherless, plead for the widow.

18Come now, and let us reason together, saith Jehovah: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. 19If ye be willing and obedient, ye shall eat the good of the land: 20but if ye refuse and rebel, ye shall be devoured with the sword; for the mouth of Jehovah hath spoken it.
