וְעַתָּ֗ה קְח֨וּ וַעֲשׂ֜וּ עֲגָלָ֤ה חֲדָשָׁה֙ אֶחָ֔ת וּשְׁתֵּ֤י פָרוֹת֙ עָל֔וֹת אֲשֶׁ֛ר לֹא־עָלָ֥ה עֲלֵיהֶ֖ם עֹ֑ל וַאֲסַרְתֶּ֤ם אֶת־הַפָּרוֹת֙ בָּעֲגָלָ֔ה וַהֲשֵׁיבֹתֶ֧ם בְּנֵיהֶ֛ם מֵאַחֲרֵיהֶ֖ם הַבָּֽיְתָה׃
"Agora, peguem e preparem um carro novo e duas vacas que ainda amamentam, sobre as quais nenhum jugo foi colocado, e prendam as vacas ao carro, e levem seus bezerros de volta para casa.
Rashi
