What became of Chileab ben David HaMelekh?
Shmuel II - II Samuel - Chapter 3:3 And his second, Chileab, of Abigail the wife of Nabal the Carmelite; and the third, Absalom the son of Maacah the daughter of Talmai the king of Geshur.
and his second, Chileab of Abigail: Elsewhere the Scripture calls him: “And his second, Daniel” (I Chron. 3:1). Said Rabbi Isaac: Since the scorners of the generation were saying that Abigail was pregnant from Nabal, his features were changed, so that he resembled his father. And our Rabbis said that he would embarrass (מכלים) Mephibosheth in legal matters.
What became of Chileab ben David HaMelekh? Did he serve in Shlomo's kingdom? As per Rashi, how did Chileab ben David HaMelekh "embarrass (מכלים) Mephibosheth in legal matters"? Why is he called "Daniel" in a different passage, I Chron. 3:1? Where does Rashi source his answer to this last question?
