וּקְח֧וּ אֶת־אֲבִיכֶ֛ם וְאֶת־בָּתֵּיכֶ֖ם וּבֹ֣אוּ אֵלָ֑י וְאֶתְּנָ֣ה לָכֶ֗ם אֶת־טוּב֙ אֶ֣רֶץ מִצְרַ֔יִם וְאִכְל֖וּ אֶת־חֵ֥לֶב הָאָֽרֶץ׃
Emmenez votre père et vos familles et venez près de moi; je veux vous donner la meilleure province de l’Égypte, vous consommerez la moelle de ce pays.
Mishnah Oholot
One who searches, must search over a square cubit and then leave a cubit, [digging down] until he reaches rock or virgin soil. [A priest] carrying out earth from a place of uncleanness may eat his terumah mixed with hullin. But one who is clearing away a heap of stones, may not eat his terumah mixed with hullin.
