Shimon HaTzaddik was [one] of the remnants of the Great Assembly. He used to say: The world stands upon three things: up-on Torah, upon the [Divine] service, and upon acts of kindness.

Antigenos, leader of Socho, received [the Mesorah] from Shimon HaTzaddik.  He used to say: Do not be like servants who serve the master for the sake of receiving a reward, but [rather] be like servants who serve the master not for the sake of re-ceiving a reward, and the fear of Heaven should be upon you.
