Rabbi Dosa ben Harkinas רבי דוסא בן הרכינס

When Rabban Gamliel ordered Rabbi Yehoshua to appear with staff and purse on the day that fell, by his reckoning, on Yom Kippur, it was Rabbi Dosa who said the deciding word: "if we re-judge the court of Rabban Gamliel, we must re-judge every court since the days of Moses"—every court in its generation is as the court of Moses in his. Rabbi Yehoshua took his staff and went.

In old age, when his eyes had grown weak, he received the sages of the new generation and knew them by their fathers' voices. His words in Avot are known by heart: "morning sleep, midday wine, children's chatter and sitting in the meeting-places of the ignorant put a man out of the world".
