You know Abner son of Ner; he came to deceive you and observe your movements and find out everything you are doing."
Joab then left David and sent messengers after Abner, and they brought him back from the well of Sirah. But David did not know it.
Now when Abner1 returned to Hebron, Joab took him aside into the gateway, as though to speak with him privately. And there, to avenge the blood of his brother Asahel, Joab stabbed him2 in the stomach, and he died.328
Later, when David heard about this, he said, "I and my kingdom are forever innocent4 before the LORD concerning the blood of Abner son of Ner.
May his blood5 fall upon the head of Joab and upon all his father's house!6 May Joab's house never be without someone who has a running sore7 or leprosya or who leans on a crutch or who falls by the sword or who lacks food."
(Joab and his brother Abishai murdered Abner because he had killed their brother Asahel in the battle at Gibeon.)
Then David said to Joab and all the people with him, "Tear your clothes and put on sackcloth8 and walk in mourning9 in front of Abner." King David himself walked behind the bier.
They buried Abner in Hebron, and the king wept10 aloud at Abner's tomb. All the people wept also.
The king sang this lament11 for Abner: "Should Abner have died as the lawless die?
Your hands were not bound, your feet were not fettered.12 You fell as one falls before wicked men." And all the people wept over him again.
Then they all came and urged David to eat something while it was still day; but David took an oath, saying, "May God deal with me, be it ever so severely,13 if I taste bread14 or anything else before the sun sets!"
