But Amasa did not observe the sword which was in Joab's hand; so Joab struck him with it in the body, and shed his bowels to the ground, without striking a second blow; and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
I am one of those who are peaceable and faithful in Israel; you seek to destroy a city which is a mother in Israel; why will you swallow up the heritage of the Lord?”
That is not true. But a man of the hill country of Ephraim, called Sheba the son of Bichri, has lifted up his hand against King David; give up him alone, and I will withdraw from the city.” And the woman said to Joab, “Behold, his head shall be thrown to you over the wall.”
and said, “Far be it from me, O Lord, that I should do this. Shall I drink the blood of the men who went at the risk of their lives?” Therefore he would not drink it. These things did the three mighty men.
