And now, O Jehovah, the God of Israel, keep with Your servant David my father that which You have promised him, saying, There shall not fail you a man in My sight to sit on the throne of Israel, if only your sons take heed to their way to walk in My Law, as you have walked before Me.

But he did not kill their sons, but as it is written in the Law in the book of Moses, where Jehovah commanded, saying, The father shall not die for the sons, nor shall the sons die for the fathers, but every man shall die for his own sin.
