Then David said to the messenger, “Tell Joab this, ‘Do not let this thing disturb you, for the sword devours one [side] as well as another. Strengthen your battle against the city and overthrow it’; and so encourage Joab.”

Your maidservant had two sons, but the two of them struggled and fought in the field. There was no one to separate them, so one struck the other and killed him.

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.”

Then the lookout saw another man running, and he called to the gatekeeper and said, “Look, another man running alone.” The king said, “He also is bringing good news.”

But Amasa [who had replaced Joab as David’s commander] was off guard and not attentive to the sword in Joab’s hand. So Joab struck Amasa in the abdomen with the sword, spilling his intestines to the ground. Without another blow Amasa died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
