'Second' in the Bible

his second, Chileab, by Abigail the widow of Nabal of Carmel; the third, Absalom the son of [his wife] Maacah, daughter of Talmai the king of Geshur;

So Ish-bosheth sent and took her from her husband, from Paltiel the son of Laish [to whom Saul had given her].

So Absalom sent for Joab, to send him to the king, but he would not come to him; even when he sent again a second time, he [still] would not come.
