^ We have here one eminent example of Nero's mildness and goodness in his government towards the Jews, during the first five years of his reign, so famous in antiquity; we have perhaps another in Josephus's own Life, sect. 3; and a third, though of a very different nature here,
in sect. 9, just before. However, both the generous acts of kindness were obtained of Nero by his queen Poppea, who was a religious lady, and perhaps privately a Jewish proselyte, and so were not owing entirely to Nero's own goodness.
