'Second' in the Bible

and his second, Chileab, of Abigail the wife of Nabal the Carmelite; and the third, Absalom the son of Maachah, daughter of Talmai king of Geshur;

Then Absalom sent for Joab, to send him to the king; but he would not come to him; and he sent again the second time, but he would not come.
