1 Kings 4:5

And Azariah the son of Nathan [was] over the officers
The twelve officers who provided food for Solomon's household after mentioned:

and Zabud the son of Nathan;
another of the sons of Nathan the prophet: for he being a principal instrument of settling Solomon on the throne, had interest enough to promote his sons to the chief places of honour and trust: and this here

[was] principal officer, [and] the king's friend;
a chief minister about him, very intimate with him, that kept him company, privately conversed with him, was in his secrets, and admitted to great privacy and nearness to him.
