Commentators agree that when Hezekiah says "by these things men live," he is referring to more than physical necessities. True life, for both body and spirit, is sustained by God's promises, His word, and His faithful intervention. Scholars like Ellicott and Gill connect this directly to Deuteronomy 8:3, reminding believers that we do not live by bread alone, but by the gracious and powerful acts of God.
