וְלֹֽא־יֵרָאֶ֨ה לְךָ֥ שְׂאֹ֛ר בְּכָל־גְּבֻלְךָ֖ שִׁבְעַ֣ת יָמִ֑ים וְלֹא־יָלִ֣ין מִן־הַבָּשָׂ֗ר אֲשֶׁ֨ר תִּזְבַּ֥ח בָּעֶ֛רֶב בַּיּ֥וֹם הָרִאשׁ֖וֹן לַבֹּֽקֶר׃
Tujuh hari lamanya janganlah ada ragi terlihat padamu di seluruh wilayahmu; dan dari daging yang engkau sembelih pada petang hari, pada hari pertama, janganlah ada yang tersisa semalaman sampai pagi.
Mishnah Beitzah
An egg laid on Yom Tov: Bet Shammai say: it may be eaten [on the same day]; But Bet Hillel say: it may not be eaten [until the day is over]. Bet Shammai say: [the quantity of] leaven is of the size of an olive and leavened bread is of the size of a date; But Bet Hillel say: both are of the size of an olive.
