2 Samuel 18:19-20

Thomson(i) 19 Then Achimaas son of Sadok said, Let me, I pray thee, run and tell the king good news, That the Lord hath delivered him out of the hand of his enemies. 20 But Joab said to him, Thou wilt not be the messenger of good news today. At another time thou shalt carry good news. But this day thou canst not be the messenger of good news, because the king's son is dead.
