Though they are red like crimson, they shall be as wool. 19 If you are willing and obedient, you will eat the good of the land; 20 but if you refuse and rebel, you will be devoured with the sword; for the LORD’s mouth has spoken it.” 21 How the faithful city has become a prostitute! She was full of justice. Righteousness lodged in her, but now there are murderers.
