("Six things Rabbi Akiva commanded Rabbi Shimon bar Yochai when he was imprisoned... He began and said to him: When you teach your sons (Torah), teach them from a carefully edited book, and if you seek to be hanged, hang from a great tree, and do not cook in a pot where your friend cooked, and do not enter a city or your house suddenly, and all the more so your friend's house. If your daughter is grown, free your servant and marry him to her, and do not hasten your feet to your friend's house" – Otzar HaMidrashim (Eisenstein), Chuppat Eliyahu, 174)
