2 Samuel 18:20-22

Amplified Bible

²⁰ But Joab told him, “You are not the man to carry news [to King David] today, but you shall carry news another day. On this day you shall carry no news, because the king’s son is dead.” ²¹ Then Joab said to the Cushite (Ethiopian), “Go, tell the king what you have seen.” And the Cushite bowed to Joab and ran. ²² Then Ahimaaz the son of Zadok said again to Joab, “But whatever happens, please let me also run after the Cushite.” Joab said, “Why should you run, my son, seeing you will have no messenger’s reward for going [because you have only bad news]?”
