2 Samuel 3:28-31 New American Bible, Revised Edition (NABRE)

28. Later David heard of it and said: “Before the Lord, I and my kingdom are forever innocent.

29. May the blood of Abner, son of Ner, be on the head of Joab and all his family. May Joab’s family never be without one suffering from a discharge, or one with a skin disease, or a man who holds the distaff, or one falling by the sword, or one in need of food!”

30. Joab and Abishai his brother had been lying in wait for Abner because he killed Asahel their brother in battle at Gibeon.

31. Then David said to Joab and to all the people who were with him, “Tear your garments, put on sackcloth, and mourn over Abner.” King David himself followed the bier.
