Saying,
Touch not my anointed, and do my prophets no harm.
All Commentaries on Psalms 105:15 Go To Psalms 105
Augustine of Hippo
AD 430
8. "What time as they went from one nation to another, from one kingdom to another people" (ver. 13). This is a repetition of what he had said, "from one nation to another." "He suffered no man to do them harm: but reproved even kings for their sakes" (ver. 14). "Touch not," He said, "Mine anointed, and do My prophets no harm" (ver. 15). He declareth the words of God chiding or reproving kings, that they might not harm the holy fathers, while they were small in number, very few, and they strangers in the land of Canaan. Although these words be not read in the books of that history, yet they are to be understood as either secretly spoken, as God speaketh in the hearts of men by unseen and true visions, or even as announced through an Angel. For both the king of Gerar and the king of the Egyptians were warned from Heaven not to harm Abraham, and another king not to harm Isaac, and others not to harm Jacob; while they were very few, and strangers, before he went over into Egypt to sojourn with his sons: which is understood to be herein mentioned. But since it occurred to ask, before they passed over and multiplied in Egypt, how so few in number, and those strangers in a foreign land, could maintain themselves: he next addeth, "He suffered no man to do them wrong," etc.
9. But it may well excite a question, in what sense they were styled (Christs, or) anointed, before there was any unction, from which this title was given to the kings? ...Whence then were those patriarchs at that tithe called "anointed"? For that they were prophets, we read concerning Abraham; and certainly, what is manifestly said of him, should be understood of them also. Are they styled "christs," because, even though secretly, yet they were already Christians? For although the flesh of Christ came from them, nevertheless Christ came before them; for He thus answered the Jews, "Before Abraham was, I am." But how could they not know Him, or not believe in Him; since they are called prophets for this very reason, because, though somewhat darkly, they announced the Lord beforehand? Whence He saith Himself openly, "Your father Abraham desired to see My day, and he saw it, and was glad." For no man was ever reconciled unto God outside of that faith which is in Christ Jesus, either before His Incarnation, or after: as it is most truly defined by the Apostle: "For there is one God, and one Mediator between God and men, the Man Christ Jesus."
