Isaiah 1:12-20

When ye come to appear before me, who hath required this at your hand, to trample my courts? Bring no more vain oblations; incense is an abomination unto me; new moon and sabbath, the calling of assemblies,—I cannot away with iniquity and the solemn meeting. Your new moons and your appointed feasts my soul hateth; they are a trouble unto me; I am weary of bearing them. And when ye spread forth your hands, I will hide mine eyes from you; yea, when ye make many prayers, I will not hear: your hands are full of blood. Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil; learn to do well; seek justice, relieve the oppressed, judge the fatherless, plead for the widow. Come 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. If ye be willing and obedient, ye shall eat the good of the land: but if ye refuse and rebel, ye shall be devoured with the sword; for the mouth of Jehovah hath spoken it.
