30 · מְנָחוֹת י״א:א · Menachos 11:1
שְׁתֵּי הַלֶּחֶם נִלּוֹשׁוֹת אַחַת אַחַת, וְנֶאֱפוֹת אַחַת אַחַת.
לֶחֶם הַפָּנִים נִלּוֹשׁ אֶחָד אֶחָד, וְנֶאֱפֶה שְׁנַיִם שְׁנָיִם.
וּבִטְפוּס הָיָה עוֹשֶׂה אוֹתָן.
וּכְשֶׁהוּא רָדָן, נוֹתְנָן בִּטְפוּס, כְּדֵי שֶׁלֹּא יִתְקַלְקְלוּ.
The two loaves: kneaded one by one, baked one by one. The Lechem HaPanim: kneaded one by one, baked two by two. [Both] prepared in a mold. When removing [from the oven] — placed in a mold so their shape would not be ruined.
