EXOD349 Lest a man should say, “Since some scholars declare a thing impure and others declare it pure, some pronounce a thing to be forbidden and others pronounce it to be permitted, some disqualify an object while others uphold its fitness, how can I study Torah under such circumstances?” Scripture states, “They are given from one shepherd” (Ecclesiastes 12:11): One God has given them, one leader [Moses] has uttered them at the command of the Lord of all creation, blessed be He, as it says, “And God spoke all these words” (Exodus 20:1). You, then, should, on your part, make your ear like a grain receiver and acquire a heart that can understand the words of the scholars who declare a thing impure as well as those who declare it pure, the words of those who declare a thing forbidden as well as those who pronounce it permitted, and the words of those who disqualify an object as well as those who uphold its fitness. Although one scholar offers his view and another offers his, the words of both are all derived from what Moses, the shepherd, received from the One Lord of the Universe. Midrash, Numbers Rabbah 14:4
