'Second' in the Bible

and his second, Chileab, of Abigail the wife of Nabal the Carmelite; and the third, Absalom the son of Maacah the 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 a second time, but he would not come.
