Vayechi

 From the book of Genesis tells one of the stories about the life of Jacob with the success of his son named Joseph and Joseph lived (Vaichi, meaning "and he lived") the last 17 years of his life in Egypt.

Vayechi means living or living, although in this parsha begins with the story of the days of Jacob's death.

Jacob organized his family into tribes to prepare them for their divine mission and then passed on to each tribe unique divine characteristics. 

Jacob's years, reunited with his family, spent in Egypt, were the best years of his life.

Although Jacob rejoiced to see his family reunited and remained faithful to the teachings of his ancestors, it is still difficult to imagine how the years he spent in the pagan environment of Egypt could have been the best years of his life.

The answer to this riddle is that, as mentioned earlier, Jacob had sent Judah to establish a Torah learning institution (yeshiva) in Egypt.

In doing so, Jacob ensured that Ida and her descendants would be spared the negative influences of corrupt Egyptian society.

By rejecting the customs of Egyptian society, Jacob’s children grew up in a way that can only happen when we are faced with challenges.

This is why Jacob’s best years were those spent in Egypt, for it was there that he could see that his children had fully absorbed his moral teachings.
