וּבַחַגִּ֣ים וּבַמּוֹעֲדִ֗ים תִּהְיֶ֤ה הַמִּנְחָה֙ אֵיפָ֤ה לַפָּר֙ וְאֵיפָ֣ה לָאַ֔יִל וְלַכְּבָשִׂ֖ים מַתַּ֣ת יָד֑וֹ וְשֶׁ֖מֶן הִ֥ין לָאֵיפָֽה׃ (ס)
And in the feasts and in the appointed seasons the meal-offering shall be an ephah for a bullock, and an ephah for a ram, and for the lambs as he is able to give, and a hin of oil to an ephah.

"shall there be unto you": Appoint a market commissioner to this end. R. Elazar b. Chananiah b. Chizkiah b. Gurion says: It is written (Ezekiel 46:11) ("the meal-offering,) an ephah (measure) for a bull and an ephah for a ram." Now is the measure for a bull and a ram and a sheep the same? We are hereby apprised that both the large ephah and the small ephah are called "ephah."
