16 Wash and make yourselves clean.
Take your evil deeds out of my sight;
stop doing wrong.
17 Learn to do right; seek justice.
Defend the oppressed.
Take up the cause of the fatherless;
plead the case of the widow.
18 “Come now, let us settle the matter,”
says the Lord.
“Though your sins are like scarlet,
they shall be as white as snow;
though they are red as crimson,
they shall be like wool.
Isaiah 1:16-18 (NIV)
