Letter 153: Reports from Babylas confirm that legal study has not made them abandon self-control.

Those who came around wisest Babylas eagerly told me the things I pray to hear, though I knew them before they spoke. Since, while studying with me, you adorned zeal for words with self-control of character and the other virtues, it was surely clear that even when you set out for the sake of law you would remain yourselves, and would perhaps become still more eager to run upward toward what is better. If that already prepares pleasure for me, what should I say, may it be said with God's help, when courts are set before you and with a disciplined tongue you pour out good order, mastering those present by experience and those far away by reputation? While these things are reported, Polycrates will seem small to me for good fortune, and Croesus, with his many talents, will seem nothing alongside it.
