משנה אויף יחזקאל 20:37

They measure [the Shabbat limit] only through an expert. If he extended the limit at one point and limited it at another, they observe the place where he extended it. If there was one who made it a greater distance and one who made it a lesser distance, the greater distance is observed. Even a slave and even a female slave are believed when they say, “Thus far is the Shabbat limit”, since the sages did not enact the law in order to be strict but in order to be lenient.

There were in the Temple thirteen chests, thirteen tables and thirteen prostrations. [Members] of the household of Rabban Gamaliel and of Rabbi Hananiah the chief of the priests used would prostrate fourteen [times. And where was the additional [prostration]? In front of the wood storage yard, for they had a tradition from their forefathers that the Ark was hidden there.
