2 Samuel 13:33
Now therefore let not my lord the king take the thing to his heart, to think that all the king’s sons are dead: for Amnon only is dead. Now therefore let not my lord the king take the thing to his heart, to think that all the king’s sons are dead: for Amnon only is dead.
The reassurance given to the king was that the alarming report was false, for not all of his sons had been killed but Amnon alone had died, and he was not to take to heart the thought that all were dead. In that moment David grieved both the murder of Amnon and the absence of Absalom.
The verse stands within the sad history of Amnon and Tamar, bound up with Amnon's death and Absalom's violence against David's household. It belongs to the sorrow and disgrace brought upon David by the deeds of his sons Amnon and Absalom. It is part of the record of David's family troubles found in chapters 13 to 20, belonging to his later history.
Those family troubles grew out of his taking many wives. They were the retribution and judgments that followed David's wrongs, above all his great sin involving Uriah, fulfilling Nathan's denunciation against him. In this way the verse illustrates that sin brings consequences in its own kind. It teaches that no one can violate God's laws without suffering, because every transgression carries an inherent curse.
