וּקְח֧וּ אֶת־אֲבִיכֶ֛ם וְאֶת־בָּתֵּיכֶ֖ם וּבֹ֣אוּ אֵלָ֑י וְאֶתְּנָ֣ה לָכֶ֗ם אֶת־טוּב֙ אֶ֣רֶץ מִצְרַ֔יִם וְאִכְל֖וּ אֶת־חֵ֥לֶב הָאָֽרֶץ׃
Y tomad á vuestro padre y vuestras familias, y venid á mí, que yo os daré lo bueno de la tierra de Egipto y comeréis la grosura de la tierra.
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.
