Charles Ellicott Commentary Isaiah 32:1

"Behold, a king shall reign in righteousness, and princes shall rule in justice." — Isaiah 32:1 (ASV)

Behold, a king shall reign ... — More accurately, the king.Isaiah 32:1–8 form a separate section, standing in the same relation to the preceding chapter that the picture of the ideal king in Isaiah 11 does to the anti-Assyrian prophecy of Isaiah 10.

“The king” is accordingly the true Anointed one of the future—not, of course, without a reference to the character of Hezekiah as the partial and present embodiment of the idea. The addition of “princes” worthy of their king emphasizes this reference. The words are as an echo of Proverbs 8:15-16.
