Matthew Henry on 1 Kings 4:1-19
Here we have,
I. Solomon upon his throne (Kg1 4:1): So king Solomon was king, that is, he was confirmed and established king over all Israel, and not, as his successors, only over two tribes. He was a king, that is, he did the work and duty of a king, with the wisdom God had given him. Those preserve the name and honour of their place that mind the business of it and make conscience of it.

John Gill on 1 Kings 4:2
And these were the princes which he had,.... That were in office about him, in the highest posts of honour and trust:
Azariah the son of Zadok the priest: or rather his grandson, since Ahimaaz was the son of Zadok, and Azariah the son of Ahimaaz, 1 Chronicles 6:8; though another Zadok may be meant, and his son not a priest but a prince, as the word may be rendered, and was Solomon's prime minister of state, and the rather, since he is mentioned first.
