NASB
"But Amasa was not on guard against the sword which was in Joab's hand so he struck him in the belly with it and poured out his inward parts on the ground, and did not strike him again, and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri."
— 2 Samuel 20:10, NASB
“But Amasa took no heed to the sword that was in Joab's hand. So he struck him with it in the body, and shed out his bowels to the ground, and didn't strike him again; and he died. Joab and Abishai his brother pursued after Sheba the son of Bichri.”
“Amasa did not protect himself from the knife in Joab’s other hand, and Joab stabbed him in the abdomen, causing Amasa’s intestines to spill out on the ground. There was no need to stab him again; the first blow was fatal. Then Joab and his brother Abishai pursued Sheba son of Bicri.”
So Joab's men went out after him, along with the Cherethites and the Pelethites and all the mighty men; and they went out from Jerusalem to pursue Sheba the son of Bichri.
When they were at the large stone which is in Gibeon, Amasa came to meet them. Now Joab was dressed in his military attire, and over it was a belt with a sword in its sheath fastened at his waist; and as he went forward, it fell out.
Joab said to Amasa, "Is it well with you, my brother?" And Joab took Amasa by the beard with his right hand to kiss him.
But Amasa was not on guard against the sword which was in Joab's hand so he struck him in the belly with it and poured out his inward parts on the ground, and did not strike him again, and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
Now there stood by him one of Joab's young men, and said, "Whoever favors Joab and whoever is for David, let him follow Joab."
But Amasa lay wallowing in his blood in the middle of the highway. And when the man saw that all the people stood still, he removed Amasa from the highway into the field and threw a garment over him when he saw that everyone who came by him stood still.
As soon as he was removed from the highway, all the men passed on after Joab to pursue Sheba the son of Bichri.
