[544] Now there was a certain old soldier of the king's, whose name was Tero, who had a son that was very familiar with and a friend to Alexander, and who himself particularly loved the young men. This soldier was in a manner distracted, out of the excess of the indignation he had at what was doing; and at first he cried out aloud, as he went about, that justice was trampled under foot; that truth was perished, and nature confounded; and that the life of man was full of iniquity, and every thing else that passion could suggest to a man who spared not his own life; and at last he ventured to go to the king, and said, "Truly I think thou art a most miserable man, when thou hearkenest to most wicked wretches, against those that ought to be dearest to thee; since thou hast frequently resolved that Pheroras and Salome should be put to death, and yet believest them against thy sons; while these, by cutting off the succession of thine own sons, leave all wholly to Antipater, and thereby choose to have thee such a king as may be thoroughly in their own power. However, consider whether this death of Antipater's brethren will not make him hated by the soldiers; for there is nobody but commiserates the young men; and of the captains, a great many show their indignation at it openly." Upon his saying this, he named those that had such indignation; but the king ordered those men, with Tero himself and his son, to be seized upon immediately.
