Proverbs 20:9-11

American Standard Version

⁹ Who can say, I have made my heart clean,
I am pure from my sin?
^10 [a]Diverse weights, and diverse measures,
Both of them alike are an abomination to Jehovah.
¹¹ Even a child maketh himself known by his doings,
Whether his work be pure, and whether it be right.
