Jerome : Verse 14. "And when the king heard this statement, he became quite grieved and applied himself on Daniel's behalf that he might deliver him." He realized that he had been tripped up by his own reply to their question, and also that envy was the motive of their plot. And so to avoid the appearance of acting against his own law, he wanted to deliver Daniel from danger by ingenuity and strategy rather than by exerting his royal authority. And so earnestly did he labor and strive that he would not accept any food, absolute monarch though he was, even until sunset. And as for the plotters, so firmly did they persist in their evil purpose that no consideration of the king's personal desire or of the damage he would sustain had any effect upon them. — St. Jerome, Commentary on Daniel, CHAPTER SIX
