Proverbs 20:9 Meaning

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

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

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

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

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