Proverbs 20:9

7 The just walketh in his integrity: his children blessed after him.

8 A king that sitteth in the throne of judgment scattereth away all evil with his eyes.

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

10 Divers weights, divers measures, both of them alike abomination to the Yahuah.

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