Proverbs 20:9-11

Authorized (King James) Version

⁹ Who can say, I have made my heart clean,
    I am pure from my sin?

¹⁰ Divers weights, and divers measures,
    both of them are alike abomination to the Lord.

¹¹ Even a child is known by his doings,
    whether his work be pure, and whether it be right.
