John Chrysostom
The humility of God is profound, and the ingratitude of the king is stark. When the prophet spoke, the king should have had no doubts about the message. Even if he had reservations, he ought to have accepted the sign and believed, as many among the Jewish people did. God, in His incarnation, rarely withheld such assurances from those who were earthly-minded and indulgent, as seen in the story of Gideon. Given that Ahaz was particularly flawed and rather dismissive, observe how God once more extends His grace towards him. The Lord Himself invites Ahaz to request a sign, revealing not only his innermost thoughts but also laying bare his entire disposition and any facade he might maintain. Refer to Isaiah 7:13 for further insight.
