18
And come, let us reason together, saith the Lord: and though your sins be as purple, I will make them white as snow; and though they be as scarlet, I will make white as wool.
16
Wash you, be clean; remove your iniquities from your souls before mine eyes; cease from your iniquities;
17
learn to do well; diligently seek judgment, deliver him that is suffering wrong, plead for the orphan, and obtain justice for the widow.
18
And come, let us reason together, saith the Lord: and though your sins be as purple, I will make them white as snow; and though they be as scarlet, I will make white as wool.
19
And if ye be willing, and hearken to me, ye shall eat the good of the land:
20
but if ye be not willing, nor hearken to me, a sword shall devour you: for the mouth of the Lord has spoken this.
