Isaiah 1:17-19 New Revised Standard Version, Anglicised (NRSVA)
17 learn to do good;
rescue the oppressed,
defend the orphan,
plead for the widow.
18 Come now, let us argue it out,
says the Lord:
though your sins are like scarlet,
they shall be like 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;
