John Chrysostom
Upon the king's realization, I assert, due to the strength of his spirit, he desired to adorn him with his own royal vestments.
And Saul clothed David with his garments, and put a helmet of brass upon his head, and armed him with a coat of mail.
וַיַּלְבֵּ֨שׁ שָׁא֤וּל אֶת־דָּוִד֙ מַדָּ֔יו וְנָתַ֛ן ק֥וֹבַע נְחֹ֖שֶׁת עַל־רֹאשׁ֑וֹ וַיַּלְבֵּ֥שׁ אֹת֖וֹ שִׁרְיֽוֹן׃
2 Church Fathers comment on this verse
Upon the king's realization, I assert, due to the strength of his spirit, he desired to adorn him with his own royal vestments.
At times, we observe that a virtuous act can lead to negative consequences. If an individual believes they are performing the same action but lacks the right disposition, intention, or are driven by a different form of virtue, they may easily become ensnared in deception and ruin, even as others gain eternal life from those very actions. The courageous young warrior who confronted the formidable giant would have faced dire outcomes had he engaged in battle donning the heavy armor of Saul, which was suited for an experienced man capable of defeating many adversaries. Had he not wisely selected armor appropriate for his youth and approached his formidable opponent not with conventional armor and shields, like the others, but with the weapons he was equipped to wield, he would have encountered certain calamity.
