2 Samuel 3:27-29
27 And when Abner had come again into Hebron, Joab led him asides half to the middle of the gate, (as if) that he should speak to him in guile; and he smote Abner there in the share-bone, and he was dead, into vengeance of the blood of his brother Asahel (and Joab struck, or stabbed, Abner in the belly, and he died there, in revenge for killing Joab’s brother Asahel).
28 That when David had heard this thing done, he said, I am clean, and my realm, with God into without end from the blood of Abner, the son of Ner; (And when David had heard that this thing was done, he said, I and my kingdom, be clean with God forevermore, of the blood, or of the murder, of Abner, the son of Ner;)
29 and come it on the head of Joab, and upon all the house of his father; and fail there not from the house of Joab a man suffering flowing of seed, and a leprous man, (and a man) holding a spindle, and a man falling by sword, and (a man) having need to bread. (yea, let it come upon Joab’s head, and upon all his father’s family; and let there never fail to be in the house of Joab a man suffering the flowing out of his seed, or a leprous man, or a man holding a spindle, or a man falling by the sword, or a man having need of bread.)Read full chapter
