1.....(4.7)
You sons of men...
A.
In this verse, David was saying to Doeg and Ahithophel, O you sons of such renowned men as Avraham, Izchok and Yakov, how long will you turn my glory into shame.
B.....(4.8)
Why are the nations of the earth called the sons of man? Because they are descendants of Noah's children's children. By man is meant the renowned Noah of whom it is said: "Noah was a righteous man he was perfect in his generations; Noah walked with God." (Bereishit - Genesis 6:9)
2.....(4.8)
how long will my honor be disgraced?
This is, how long will you turn the glory of my own name into shame by calling me the son of Jesse, as when Doeg says: "I saw the son of Jesse..." (Shmuel I - I Samuel 22:9), or as Soul says to Jonathan: "Did I not know that you choose the son of Jesse, to your shame and to the shame of your mother's nakedness?".
Have I no name of my own?
3.....(4.8)
You love vanity and seek deception
This is, David said to Doeg and Ahithophel, How long will you abuse me with vain and empty words, saying of me, God has abandoned him, God has forgotten him, God has taken His presence away from him, and henceforth kingship will never return to him. You expect the loss to continue forever? David meant, Long ago, God gladdened me with good tidings through Nathan the prophet, who told me: "Also the Lord has removed your sin; you shall not die." (Shmuel II - II Samuel 12:13)
