Asperges me, Domine, hyssopo, et mundabor:
Lavabis me, et super nivem dealbabor.
I was just now quickly reading through posts, when these last two lines caught my eye.
I thought perhaps it would not be off topic to post my understanding of these lines, since some readers may be puzzled and curious.
They are the Latin translation of the 51st Psalm of David: "Sprinkle me, O Lord, with hyssop (rosehips), and I shall be cleansed. Wash me and I shall become whiter than snow."
Your nick, "Septuaginarian", meaning a person in their 70's,, is reminiscent of the Greek Septuagint translation of the Old Testament (supposedly done by 70 scholars), which has a slightly different numbering of the Psalms, in which the 51st of KJV becomes the 50th Psalm (the most frequently repeated Psalm in Eastern Orthodox prayers, repeated dozens of times each day).
Tradition has it that the 51st (aka 50th) Psalm was written by King David to express his sorrow and repentence over sending his friend Uriah to the front lines of a battle (knowing that Uriah would be killed), so that David might marry Bathesheba, Uriah's widow. The offspring of their tainted union was that wisest of all kings, Solomon, who, because of his unquenchable appetite for 800 wives (including idolators), brought about the division of the nation of Israel and the loss of certain tribes.
So, we see that this 50th Psalm is an apology for sexual misconduct.
Furthermore, in the Biblical accound of David, Jonathan, his "best friend", (and there is a verse which states that the love of two such "friends" transcends the love of husband and wife), rebukes David in a clever fashion, with a story about SHEEP.
Jonathan comes to David, and says, "O, King David! Do you know that in your kingdom, a great injustice has been done? There was a poor man, with only one sheep, and he loved his sheep dearly. But another man, with a multitude of sheep, stole that poor man's sheep!" David became enraged and exclaimed that that wrong-doer must be severely punished, demanding to know the trangressor's identity. Jonathan replies, "that person is YOU, David, and the poor man is Uriah, and the one stolen sheep is Bathsheba."
