[317] NOW Silas, the general of the king's horse, because he had been faithful to him under all his misfortunes, and had never refused to be a partaker with him in any of his dangers, but had oftentimes undergone the most hazardous dangers for him, was full of assurance, and thought he might expect a sort of equality with the king, on account of the firmness of the friendship he had showed to him. Accordingly, he would no where let the king sit as his superior, and took the like liberty in speaking to him upon all occasions, till he became troublesome to the king, when they were merry together, extolling himself beyond measure, and oft putting the king in mind of the severity of fortune he had undergone, that he might, by way of ostentation, demonstrate What zeal he had showed in his service; and was continually harping upon this string, what pains he had taken for him, and much enlarged still upon that subject. The repetition of this so frequently seemed to reproach the king, insomuch that he took this ungovernable liberty of talking very ill at his hands. For the commemoration of times when men have been under ignominy, is by no means agreeable to them; and he is a very silly man who is perpetually relating to a person what kindness he had done him. At last, therefore, Silas had so thoroughly provoked the king's indignation, that he acted rather out of passion than good consideration, and did not only turn Silas out of his place, as general of his horse, but sent him in bonds into his own country. But the edge of his anger wore off by length of time, and made room for more just reasonings as to his judgment about this man; and he considered how many labors he had undergone for his sake. So when Agrippa was solemnizing his birth-day, and he gave festival entertainments to all his subjects, he sent for Silas on the sudden to be his guest. But as he was a very frank man, he thought he had now a just handle given him to be angry; which he could not conceal from those that came for him, but said to them, "What honor is this the king invites me to, which I conclude will soon be over? For the king hath not let me keep those original marks of the good-will I bore him, which I once had from him; but he hath plundered me, and that unjustly also. Does he think that I can leave off that liberty of speech, which, upon the consciousness of my deserts, I shall use more loudly than before, and shall relate how many misfortunes I have been delivered from; how many labors I have undergone for him, whereby I procured him deliverance and respect; as a reward for which I have borne the hardships of bonds and a dark prison? I shall never forget this usage. Nay, perhaps, my very soul, when it is departed out of the body, will not forget the glorious actions I did on his account." This was the clamor he made, and he ordered the messengers to tell it to the king. So he perceived that Silas was incurable in his folly, and still suffered him to lie in prison.
