Commentators see a dual fulfillment in this verse. While it likely referred initially to a just king like Hezekiah, offering hope to the people of Judah, scholars like Calvin, Gill, and Henry emphasize that its ultimate and much higher fulfillment is in Jesus Christ. The establishment of this throne is not through human might but through God's 'lovingkindness' or 'mercy,' a foundational aspect of Christ's eternal kingdom.
