Isaiah 1:18-19

¹⁸And come ye, and prove ye me, saith the Lord. Though your sins be as blood-red, those shall be made white as snow; and though they be red as vermilion, they shall be white as wool. (And come ye, and prove ye me out, saith the Lord. And though your sins be as red as blood, they shall be made as white as snow; and though they be as red as vermilion, they shall be made as white as wool.)

¹⁹If ye will, and hear me, ye shall eat the goods of the earth. (If ye be willing, and obey me, then ye shall eat the good things of the earth.)
