Isaiah 1:18–20

God invites them to reason: willing and listening, or refusing and rebelling

18Come now, and let us argue it out, says YHWH. If your sins are like scarlet, they will be white as snow; if they are red like crimson, they will be like wool.

19If you are willing and listen, you will eat the good of the land;

20but if you refuse and rebel, you will be devoured by the sword, for the mouth of YHWH has spoken.

In its context

16Wash yourselves, make yourselves clean; remove the evil of your deeds from before my eyes; stop doing evil.

17Learn to do good; seek justice; set right the oppressor; judge the case of the orphan; plead the cause of the widow.

…

21How the faithful city has become a prostitute! Full of justice, righteousness lodged in her, but now murderers.

22Your silver has become dross, your liquor diluted with water.
