II Maccabees 9:17-27

17 Yea, and that also he would become a Jew himself, and go through all the world that was inhabited, and declare the power of God.
18 But for all this his pains would not cease: for the just judgment of God was come upon him: therefore despairing of his health, he wrote unto the Jews the letter underwritten, containing the form of a supplication, after this manner:
19 Antiochus, king and governor, to the good Jews his citizens wisheth much joy, health, and prosperity:
20 If ye and your children fare well, and your affairs be to your contentment, I give very great thanks to God, having my hope in heaven.
21 As for me, I was weak, or else I would have remembered kindly your honour and good will returning out of Persia, and being taken with a grievous disease, I thought it necessary to care for the common safety of all:
22 Not distrusting mine health, but having great hope to escape this sickness.
23 But considering that even my father, at what time he led an army into the high countries. appointed a successor,
24 To the end that, if any thing fell out contrary to expectation, or if any tidings were brought that were grievous, they of the land, knowing to whom the state was left, might not be troubled:
25 Again, considering how that the princes that are borderers and neighbours unto my kingdom wait for opportunities, and expect what shall be the event. I have appointed my son Antiochus king, whom I often committed and commended unto many of you, when I went up into the high provinces; to whom I have written as followeth:
26 Therefore I pray and request you to remember the benefits that I have done unto you generally, and in special, and that every man will be still faithful to me and my son.
27 For I am persuaded that he understanding my mind will favourably and graciously yield to your desires.
