David was one of the wealthiest Anglo-Jewish financiers of the 13th century. He was one of six wealthy Jews engaged by King Henry III to collect the tallage, the special tax the Crown often imposed on Jews to raise funds quickly for royal projects.
The Close Rolls in England were an administrative record of every letter and order issued with the authority of the Crown behind it. There is an entry from Winchester for 27 August, 1242:
For David of Oxford: The King to Masters Moses of London, Aaron of Canterbury, and Jacob of [Oxford], Jews, greeting. We do hereby forbid you to hold henceforth any plea concerning David Jew of Oxford and Muriel who was wife of the same; nor under any circumstances are you to distrain him either to take or to keep that wife or any other. Know for certainly that if you do otherwise, you will incur grave punishment therefore.
In short, the king forbade anyone (and those three in particular) from acting with any authority on the current issue of David and Muriel "who was wife of the same." Note the italics. David divorced Muriel, presumably because they were childless and he wanted a son to whom he could leave his fortune. Jewish law forbade divorcing a wife without her consent. Muriel (we assume) did not consent, and appealed for help.
She appealed to her family in Lincoln. Peytevin the Great, who had his own synagogue, appealed to the beth din (rabbinical court) in France (the rabbis of France were considered very authoritative). The word from France seemed to be that David acted improperly and must take Muriel back. An ad hoc beth din was assembled in Oxford of three men to ratify this decision and present it to David. We know who these men were because of another entry in the Close Rolls on the same date. I share the relevant part here:
... Moreover, Peytevin of Lincoln, Muriel who was the wife of David of Oxford, Benedict f. (son of) Peytevin of Lincoln, Vaalyn', and Moses de Barbun', Jews, are to appear before the aforesaid Archbishop and others of the King's council on the octave of St Michael, wheresoever they shall be in England, to show cause why they sent to France to the Jews of France to hold a chapter on the Jews of England. And the said justices are enjoined not to permit David of Oxford to be constrained to take or to keep any wife save of his own desire.
David, seeing the decision to overturn his divorce, obviously turned to the authority that could override the English Jews and give David what he wanted, the man who relied on David for ready money, King Henry III.
Tomorrow I'll tell you how it turned out, what happened to Muriel, and why David's second wife was imprisoned in the Tower of London.
