'Second' in the Bible

and his second, Chileab, by Abigail the widow 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. So he sent again a second time, but he would not come.
