2 Samuel 3:28-29

28Later when David heard about it, he said, “As far as the Lord is concerned, my kingdom and I are forever innocent of spilling the blood of Ner’s son Abner.

29May the blame fall on the head of Joab and all of his family. May there always be members of Joab’s family who have oozing sores and skin diseases, who can only work a spindle, who die in battle, and who never have any food.”
