2 Samuel 3:28-31 Catholic Public Domain Version (CPDV)

28. And when David had heard of it, now that the matter was done, he said: "I and my kingdom are clean before the Lord, even forever, of the blood of Abner, the son of Ner.

29. And may it fall upon the head of Joab, and upon the entire house of his father. And may there not fail to be, in the house of Joab, one who suffers from a flow of seed, or one who is leprous, or one who is effeminate, or one who falls by the sword, or one who is in need of bread."

30. And so, Joab and his brother Abishai killed Abner, because he had killed their brother Asahel at Gibeon, during the battle.

31. Then David said to Joab, and to all the people who were with him, "Tear your garments, and gird yourselves with sackcloth, and mourn before the funeral procession of Abner." Moreover, king David himself was following the casket.
