The center of the RABaD's activity was Posquières, after which place he is often called. The town is known as Vauvert today. It is difficult to determine when he moved to Posquières; but about 1165 Benjamin of Tudela, at the outset of his travels, called upon him there. He spoke of the "Ravad's" wealth and benevolence. Not only did he erect and keep in repair a large school-building, but he cared for the material welfare of the poor students as well. To this date in Vauvert a street exists with the name "Rue Ravad." His great wealth brought him into peril of his life because, to obtain some of it, Elzéar, the lord of Posquières, had him cast into prison, where, like Rabbi Meir of Rothenburg, he might have died, had not Count Roger II Trencavel, who was friendly to the Jews, intervened, and by virtue of his sovereignty banished the lord of Posquières to Carcassonne. Thereupon the "Ravad" returned to Posquières, where he remained until his death.
