Dvar Torah on Hadran of Gemara )לפי רמ"א )רבי משה איסרל"ש Chanina bar Papa was a wealthy man who, whenever he completed a tractate, used to make great celebrations to which he invited his ten sons, as well as many others. As a result, he brought glory to the Torah, which was reflected in the scholarly attainments of his sons. The nation, therefore, honors Rav Pappa and his family by mentioning them at every siyum. Esoterically, Rav Pappa represented Moshe and the names of his sons symbolize the Ten Commandments, as demonstrated below.
