252. David bade his son Solomon do two things, one concerning Joab, the other Shim'i, among the other commands he bade him. One concerned Joab, as written, "Moreover you know also what Joab the son of Tzruyah did to me" (I Melachim 2:5). It was something unknown that even Solomon could not have known. But since others knew, Solomon found out. Hence he said, "Moreover you know," what he was not supposed to have known.
