'Third' in the Bible

On the third day a man with torn clothes and dust on his head came from Saul’s camp. When he came to David, he fell to the ground and paid homage.

his second was Chileab,by Abigail, the widow of Nabal the Carmelite;the third was Absalom,son of Maacah the daughter of King Talmai of Geshur;

He then sent out the troops, a third under Joab, a third under Joab’s brother Abishai son of Zeruiah, and a third under Ittai the Gittite. The king said to the troops, “I will also march out with you.”
