Proverbs 20:7 The just man walketh in his integrity: his children are 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?
Now we see a righteous man that lives his life everyday walking in paths God has led him in and because this man serves God everyday his children are blessed even after he is gone. Next we see a king who is ruling by the laws of God and this strikes terror in eyes of evil men and they realize the punishment they will receive for their deeds. The King of Kings, Jesus Christ, sees directly those who would stand before Him and lie.There is nothing concealed that He does not know. Last we should already know that no one can say they have made their heart clean or that they are clean of sin. The only way this can happen is to be washed in the blood of Jesus. After that a person can say that his heart is clean and that he is purified.Those whose sin has been forgiven are pure before God. We se in these verse a man who is righteous and passes it to his family, a king who works by God’s law and the respect him, and last the only way to find salvation is through Christ.
