'Older' in the Bible

But King Solomon replied to his mother, "Why are you asking Abishag the Shunammite for Adonijah? Why not ask me to give up the kingdom for him, since he's my older brother, and why not ask for Abiathar the priest, and for Zeruiah's son Joab?"

because as Solomon grew older, his wives turned his affections away after other gods, and his heart was not fully as devoted to the LORD his God as his father David's heart had been.

King Rehoboam consulted with the older advisers who had served his father Solomon when he had been alive. He asked them, "How do you advise me to answer these people?"

The king responded to the people harshly. He rejected the advice of the older men

Now a certain older prophet was living in Bethel, and his son came and recounted to him all of the things that the man of God had done that day in Bethel [and] the words he had spoken to the king, and they told them to their father.
