'Oldest' in the Bible

And their father gave them much silver and gold and things of great value, as well as walled towns in Judah; but the kingdom he gave to Jehoram, because he was the oldest.

The king went up to the Lord's temple, accompanied by all the people of Judah, the residents of Jerusalem, the priests, and the Levites. All the people were there, from the oldest to the youngest. He read aloud all the words of the scroll of the covenant that had been discovered in the Lord's temple.
