Biblical references to Challah

וְלָקַחְתָּ֣ סֹ֔לֶת וְאָפִיתָ֣ אֹתָ֔הּ שְׁתֵּ֥ים עֶשְׂרֵ֖ה חַלּ֑וֹת שְׁנֵי֙ עֶשְׂרֹנִ֔ים יִהְיֶ֖ה הַֽחַלָּ֥ה הָאֶחָֽת׃

You shall take choice flour and bake of it twelve loaves, two-tenths of a measure for each loaf.

דַּבֵּר֙ אֶל־בְּנֵ֣י יִשְׂרָאֵ֔ל וְאָמַרְתָּ֖ אֲלֵהֶ֑ם בְּבֹֽאֲכֶם֙ אֶל־הָאָ֔רֶץ אֲשֶׁ֥ר אֲנִ֛י מֵבִ֥יא אֶתְכֶ֖ם שָֽׁמָּה׃

Speak to the Israelite people and say to them:

When you enter the land to which I am taking you

וְהָיָ֕ה בַּאֲכׇלְכֶ֖ם מִלֶּ֣חֶם הָאָ֑רֶץ תָּרִ֥ימוּ תְרוּמָ֖ה לַיהֹוָֽה׃

and you eat of the bread of the land, you shall set some aside as a gift to GOD:

רֵאשִׁית֙ עֲרִסֹ֣תֵכֶ֔ם חַלָּ֖ה תָּרִ֣ימוּ תְרוּמָ֑ה כִּתְרוּמַ֣ת גֹּ֔רֶן כֵּ֖ן תָּרִ֥ימוּ אֹתָֽהּ׃

as the first yield of your baking, you shall set aside a loaf as a gift; you shall set it aside as a gift like the gift from the threshing floor.

מֵרֵאשִׁית֙ עֲרִסֹ֣תֵיכֶ֔ם תִּתְּנ֥וּ לַיהֹוָ֖ה תְּרוּמָ֑ה לְדֹרֹ֖תֵיכֶֽם׃ {ס}

You shall make a gift to GOD from the first yield of your baking, throughout the ages.
