it is useful to reflect on things written long ago for our benefit.
16 Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil, 17 learn to do good; seek justice, correct oppression; defend the fatherless, plead for the widow.
18 “Come now, let us reason together, says the Lord: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool. 19 If you are willing and obedient, you shall eat the good of the land; 20 but if you refuse and rebel, you shall be devoured by the sword; for the mouth of the Lord has spoken.”
