Reference for Eruvin 1:2

גמרא ר' יוסה אמר לה סתם רבי אחא בשם רב רבנן ילפין לה מפתחו של היכל ורבי יודה יליף לה מפתח

We recite [in our mishnah] "...from the time that the kohanim (Aaronide priests) enter to eat their Terumah (produce consecrated for priestly consumption)." Rabbi Chiya taught [in Tosefta Berakhot 1:1]: "...from the time that people usually go in to eat their bread on the eve of the Sabbath." And there is a baraita that comments on this: "These opinions are close enough to be equal."
