[240] BUT Herodias, Agrippa's sister, who now lived as wife to that Herod who was tetrarch of Galilee and Peres, took this authority of her brother in an envious manner, particularly when she saw that he had a greater dignity bestowed on him than her husband had; since, when he ran away, it was because he was not able to pay his debts; and now he was come back, he was in a way of dignity, and of great good fortune. She was therefore grieved and much displeased at so great a mutation of his affairs; and chiefly when she saw him marching among the multitude with the usual ensigns of royal authority, she was not able to conceal how miserable she was, by reason of the envy she had towards him; but she excited her husband, and desired him that he would sail to Rome, to court honors equal to his; for she said that she could not bear to live any longer, while Agrippa, the son of that Aristobulus who was condemned to die by his father, one that came to her husband in such extreme poverty, that the necessaries of life were forced to be entirely supplied him day by day; and when he fled away from his creditors by sea, he now returned a king; while he was himself the son of a king, and while the near relation he bare to royal authority called upon him to gain the like dignity, he sat still, and was contented with a privater life. "But then, Herod, although thou wast formerly not concerned to be in a lower condition than thy father from whom thou wast derived had been, yet do thou now seek after the dignity which thy kinsman hath attained to; and do not thou bear this contempt, that a man who admired thy riches should he in greater honor than thyself, nor suffer his poverty to show itself able to purchase greater things than our abundance; nor do thou esteem it other than a shameful thing to be inferior to one who, the other day, lived upon thy charity. But let us go to Rome, and let us spare no pains nor expenses, either of silver or gold, since they cannot be kept for any better use than for the obtaining of a kingdom."
