Midras Kejadian 42:3: Midrash Tanchuma, Midrash Tanchuma Buber, Bamidbar Rabbah & Pirkei DeRabbi Eliezer

As soon as Jacob heard that there was corn in Egypt, he said to his sons: Get you down thither, and buy for us from them, etc. And Joseph’s ten brethren went down (ibid. 42:2–3). Why did all ten go? Because in that number resides the power to set aside retribution.⁴Because ten comprise a minyan and so they could beseech God as a congregation. For example, when the Holy One, blessed be He, was about to destroy Sodom, our patriarch Abraham pleaded for heavenly mercy in their behalf. He spoke first of fifty men, but finally reduced the number to ten, as it is said: Peradventure ten shall be found there (ibid. 18:31). Ten men also comprise a congregation, as is said: How long shall I bear with this evil congregation (Num. 14:27), and God standeth in the congregation of God (Ps. 82:1). Hence Scripture states: Joseph’s ten brethren went down (Gen. 42:3). Just as in the case of Sodom, Scripture speaks here of ten. And the sons of Israel came to buy among those that came (Gen. 42:5), in order that no one would recognize them. The Holy One, blessed be He, declared: Because you have said: We shall see what will become of his dreams (ibid. 37:20), his dream was fulfilled. Joseph saw his brothers and recognized them, but they did not recognize him, for they had felt no compassion for him, while Joseph recognized them because he pitied them.

And God said unto Jacob: “Arise, go up to Beth-El” (Gen. 35:1). May our master teach us: How many times is a man’s “account book”⁷The heavenly ledger wherein man’s deeds are recorded. open? Thus did our masters teach us: A man’s account book is opened three times: when he journeys alone upon a highway; when he resides in a dilapidated house; when he vows and fails to fulfill. R. Aha the son of Jacob deduced the first statement from the biblical verse If harm befall him by the way (Gen. 42:3). R. Eliezer the son of R. Yosé the Galilean stated: If you should discover that a righteous man is setting out on a journey, leave even three days earlier or three days later in order to travel with him. But if you should see a wicked man setting out on a journey, leave three days earlier or three days later in order not to go with him, as it is said: Set thou a wicked man over him; and let an adversary stand at his right hand (Ps. 109:6). A righteous man, however, is accompanied by angels of peace, as it is said: For He will give his angels charge over thee (ibid. 91:11).

Jacob said unto his sons: “Why do ye look one upon another?” (Gen. 42:1). Jacob told his sons: Since you are strong and handsome, do not enter through one gate, nor stand together in one place, lest the evil eye prevail over you.⁶A belief that an envious glance may affect one’s destiny. Behold, I have heard that there is corn in Egypt. Get you down thither (ibid., v. 2). What is the meaning of the words get you down? He foresaw that they would go down and be enslaved there for two hundred and ten years, the numerical value of the letters of the word redu (“get you down”). The expression Get you down thither was employed because everyone who purchases grain in the marketplace degrades himself by doing so.⁷A sign of misfortune, since one’s own field should provide for one’s needs. And Joseph’s ten brethren went down (ibid., v. 3). Surely, the verse should read “Israel’s sons,” but it is written in this way because they did not treat him like a brother when they sold him. Later they began to regret their actions and promised each other: “When we descend to Egypt, we shall return our brother to our father.” When their father told them to go to Egypt, they all agreed to return with him.
