טַפְּכֶ֣ם נְשֵׁיכֶ֔ם וְגֵ֣רְךָ֔ אֲשֶׁ֖ר בְּקֶ֣רֶב מַחֲנֶ֑יךָ מֵחֹטֵ֣ב עֵצֶ֔יךָ עַ֖ד שֹׁאֵ֥ב מֵימֶֽיךָ׃
your little ones, your wives, and thy stranger that is in the midst of thy camp, from the hewer of thy wood unto the drawer of thy water;
Mishneh Torah, Torah Study
Some of the great scholars in Israel were hewers of wood, some of them drawers of water, and some of them blind: nevertheless they engaged themselves in the study of the Torah by day and by night. Moreover, they are included among those who translated the tradition as it was transmitted from mouth of man to mouth of man, even from the mouth of Moses our Master.
