'Senior' in the Bible

Later, Rehoboam appointed Abijah, his son from Maacah, as senior family leader among his brothers, since he intended to establish Abijah as king.

At the end of that year, the Aramean army attacked Joash. They invaded Judah and Jerusalem, destroyed every senior official among the people, and sent all of their possessions to the king of Damascus.

The number of senior leaders of the ancestral houses of his elite forces numbered 2,600.

Jehiel, Azaziah, Nahath, Asahel, Jerimoth, Jozabad, Eliel, Ismachiah, Mahath, and Benaiah served as supervisors under Conaniah and his brother Shimei, who had been appointed by King Hezekiah. Azariah served as senior officer of God's Temple.
