R. Yonathan says: This (derivation) is not needed. Is it not already written (Exodus 20:8) "Remember the Sabbath day to keep it holy, etc." Now does this not follow a fortiori, viz.: If on a Sabbath, the greater, you are not exhorted against the work of a gentile for you, how much more so on a festival, the lesser! If so, what is the intent of "All labor shall not be done in them"? Neither you nor your neighbor shall do it (for you).
