'Leading' in the Bible

Ahab had seventy sons living in Samaria. So Jehu wrote letters and sent them to Samaria to the leading officials of Jezreel and to the guardians of Ahab's dynasty. This is what the letters said,

Now the king's sons, totaling 70 men, were living with the leading men of the city, who were their guardians. When the letter from Jehu arrived, the city leaders arrested the king's sons, slaughtered all 70 of them, put their heads in baskets, and sent them to Jehu at Jezreel.

He sent Eliakim the palace supervisor, Shebna the scribe, and the leading priests, clothed in sackcloth, with this message to the prophet Isaiah son of Amoz:

Nebuchadnezzar deported Jehoiachin to Babylon. Also, he took the king’s mother, the king’s wives, his officials, and the leading men of the land into exile from Jerusalem to Babylon.
