My servant Eliakim - A man who will be faithful to me; who will be trustworthy, and to whom the interests of the city may be safely confided; a man who will not seek to betray it into the hands of the enemy. Of Eliakim we know nothing more than what is stated here, and in Isaiah 36. From that account it appears that he was prefect of the palace; that he was employed in a negotiation with the leader of the army of the Assyrians; and that he was in all things faithful to the trust reposed in him.
The son of Hilkiah - Kimchi supposes that this was the same as Azariah the son of Hilkiah, who might have had two names, and who was a ruler over the house of God in the time of Hezekiah 1 Chronicles 6:13.
