Midrasch zu Bereschit 42:3

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).

R. Joshua of Sikhnin was of the opinion that the Holy One, blessed be He, gave Abraham a sign that whatever happened to him would likewise happen to his descendants. He chose Abraham from among all those in his father’s house, as it is said: Thou art the Lord God who didst choose Abraham, and brought him forth out of Ur of the Chaldees, and gavest him the name of Abraham (Neh. 9:7). And He selected Abraham’s sons to be His chosen ones among the seventy nations, as is said: For thou art a Holy people unto the Lord thy God, and the Lord hath chosen thee to be His own treasured nation out of all the peoples that are upon the face of the earth (Deut. 14:2). He said to Abraham: Get thee, and to Abraham’s sons, He said: I will bring you up out of the affliction of Egypt unto the land of the Canaanite, and the Hittite, and the Emorite, etc. (ibid. 3:17). He promised Abraham: And I will bless thee, and make thy name great; and be thou a blessing (Gen. 12:2), and He told his sons: The Lord bless thee, and keep thee (Num. 6:24). To Abraham He said: I will make thee a great nation (Gen. 12:2), and to his descendants He said: And what great nation is there (Deut. 4:8). Concerning Abraham it is written: Abraham was one (Ezek. 33:24), and of Israel it is said: And who is like thy people Israel, a nation one in the earth (I Chron. 17:21). In reference to Abraham it is said: and hunger was in the land (Gen. 12:10), and about his descendants it is said: When they returned to Egypt, hunger was already in the land (ibid. 43:1). Abraham descended to Egypt because of famine, and his sons, also, descended because of famine, as is said: And Joseph’s ten brethren went down to buy corn from Egypt (ibid. 42:3). When Abraham descended the Egyptians approached him, and the Egyptians beheld the woman that she was very fair (ibid. 12:14), and concerning his descendants, the Egyptians declared: Come, let us deal wisely with them lest they multiply, and it come to pass, that when there befalleth us any war, they also join themselves unto our enemies, and fight against us, and get them up out of the land (Exod. 1:10).
