"Come now, and let us reason together,"
Says the Lord,
"Though your sins are as scarlet,
They will be as white as snow;
Though they are red like crimson,
They will be like wool.
Isaiah 1:18 NASB
Behold, You desire truth in the innermost being,
And in the hidden part You will make me know wisdom.
Purify me with hyssop, and I shall be clean;
Wash me, and I shall be whiter than snow.
Psalm 51:6-7 NASB
