Gen xxiv.19: Why does she say, “And for thy camels I will draw water untill they have drunk.”
“(Scripture) dwells at length on the benevolence of the teacher who wishes not only to hand over and entrust scientific knowledge (to the pupil), but to put it in order and make it stick to him, since she gives drink to his memory, of which the camels are symbols. For genuine teachers and instructors direct their teaching not to display but to the profit of their pupils, and compel them to repeat from memory what has been said by them, thus firmly impressing upon them what they have heard.”
Questions and answers on Genesis, Book iv,106.
