American Standard Version (ASV):
But Amasa took no heed to the sword that was in Joab’s hand: so he smote him therewith in the body, and shed out his bowels to the ground, and struck him not again; and he died. And Joab and Abishai his brother pursued after Sheba the son of Bichri.
King James Version (KJV):
But Amasa took no heed to the sword that [was] in Joab’s hand: so he smote him therewith in the fifth [rib], and shed out his bowels to the ground, and struck him not again; and he died. So Joab and Abishai his brother pursued after Sheba the son of Bichri.
