וַיֵּ֨רֶד יְהוָ֥ה ׀ בֶּעָנָן֮ וַיְדַבֵּ֣ר אֵלָיו֒ וַיָּ֗אצֶל מִן־הָר֙וּחַ֙ אֲשֶׁ֣ר עָלָ֔יו וַיִּתֵּ֕ן עַל־שִׁבְעִ֥ים אִ֖ישׁ הַזְּקֵנִ֑ים וַיְהִ֗י כְּנ֤וֹחַ עֲלֵיהֶם֙ הָר֔וּחַ וַיִּֽתְנַבְּא֖וּ וְלֹ֥א יָסָֽפוּ׃
Entonces SEÑOR descendió en la nube, y hablóle; y tomó del espíritu que estaba en él, y púsolo en los setenta varones ancianos; y fué que, cuando posó sobre ellos el espíritu, profetizaron, y no cesaron.
Mishnah Eruvin
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.
