ON GOOD MANNERS
"Decorum came before the giving of the Law." (By "decorum" is meant good manners.)
דרך ארץ קדמה לתורה - ויקרא רבה ט, ג
If anyone doesn't know it yet, the attached photo shows Mount Sinai where the Law (Torah) was given to Moses more than 3 millenniums ago. Even so, the people of Israel were known for their good manners long before they were given instruction from Sinai. By this we learn that the Torah (Divine Law of Moses) finds no place in a man devoid of good manners. Good manners are part and parcel of living a godly life based on the Law of Moses. The Book of Genesis is full of stories of this kind.
