Isaiah 1:16

13 Give me no more false offerings; the smoke of burning flesh is disgusting to me, so are your new moons and Sabbaths and your holy meetings.

14 Your new moons and your regular feasts are a grief to my soul: they are a weight in my spirit; I am crushed under them.

15 And when your hands are stretched out to me, my eyes will be turned away from you: even though you go on making prayers, I will not give ear: your hands are full of blood.

16 Be washed, make yourselves clean; put away the evil of your doings from before my eyes; let there be an end of sinning;

17 Take pleasure in well-doing; let your ways be upright, keep down the cruel, give a right decision for the child who has no father, see to the cause of the widow.

18 Come now, and let us have an argument together, says the Lord: how may your sins which are red like blood be white as snow? how may their dark purple seem like wool?

19 If you will give ear to my word and do it, the good things of the land will be yours;
