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;)
