As for these four young men, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams.
All Commentaries on Daniel 1:17 Go To Daniel 1
Jerome
AD 420
Note that God is said to have given the holy lads knowledge and learning in secular literature, in every book and branch of wisdom. Symmachus rendered this by "grammatical art," implying that they understood everything they read, and by the Spirit of God could make a judgment concerning the lore of the Chaldeans. But Daniel had an outstanding gift over and above the three lads, in that he could astutely discern the significance of visions and dreams in which things to come are shown forth by means of certain symbols and mysteries.
