Joseph Went Down to Egypt so Six Hundred Thousand Could Come Up
Joseph's descent from Canaan into Egypt was the first step of a multiplication the rabbis tracked from seventy souls to a nation counted at the sea.

One Man, One Road, One Coat
Joseph was seventeen years old when his brothers stripped the coat from his back and dropped him into a pit. He was the favorite son of an old man who had made the mistake of advertising the preference in cloth. His brothers had watched the coat for too long and let what they saw harden into something they acted on when the opportunity came in the Dothan fields, far from their father's tent.
The coat was striped, or long-sleeved, or many-colored: the Hebrew word has been debated across the centuries. What is agreed is that it was particular and conspicuous, the kind of garment a person wears when someone else has decided to mark them out. When the coat disappeared, seventy people began moving toward a fate that would not become fully visible for four hundred years.
The Number That Waited in Egypt
Genesis counts the family that came down to Egypt under Jacob's authority: sixty-six people, or seventy with Jacob and Joseph and his two sons already in Egypt. The tradition standardized around seventy. Midrash Tehillim reads Psalm 45's promise that sons will stand in the place of fathers as a prophecy directed at that number. Rabbi Elazar bar Rabbi Yosei traces the line from the seventy who entered Egypt to the six hundred thousand men of military age who left at the Exodus, and from that number to the future promise of even greater children.
The multiplication is not accidental in rabbinic understanding. Egypt was the furnace where the nation was formed. The pressure that produced Israel as a people required a closed space, a hostile government, forced labor, and enough time for seventy people to become a mass too large to ignore. Joseph's descent into Egypt was not only his personal misfortune. It was the mechanism.
The Coat and the Sea
The aggadic tradition makes a formal connection between the coat and the miracle at the sea. The color and the pattern of Joseph's garment reappear in the imagery of the splitting waters. The rabbis of the Mekhilta tracked this as a record of correspondence: what was done to Joseph in Canaan echoed across centuries until the sea opened and the people who descended from his father's household walked through on dry ground. The coat that was torn off began a chain of events that ended in the sea tearing open.
Joseph himself understood something of this. Genesis 50:25 records that before he died he made Israel swear to carry his bones out of Egypt when the time came. He did not ask this because he was uncertain about the promise. He asked it because he knew the promise would be kept and he wanted his bones present at the fulfillment of what his descent had set in motion.
Counting Toward a Promise
The Mekhilta tractate Bachodesh preserves the tradition associated with Rabbi Eliezer: that Israel was counted ten times across the long span of its history, from the entry into Egypt to the age yet to come. The counts are not bureaucratic exercises. Each one marks a moment when the nation was assessed, organized, and prepared for what came next. The six hundred thousand at the Exodus are the central count, the one against which all others are measured.
Psalm 45 says that sons will stand in the place of fathers, and the rabbis heard in that verse the full scope of the Josephite promise: children arising from the nation Joseph's descent made possible, taking the place of the fathers who were counted at the sea, in the camp, in the wilderness, and in the end in the land.
