Liturgy sur La Genèse 47:4

"And he went down to Egypt" - helpless on account of the word [in which God told Avraham that his descendants would have to go into exile]. "And he resided there" - [this] teaches that Ya'akov, our father, didn't go down to settle in Egypt, but rather [only] to reside there, as it is stated (Genesis 47:4), "And they said to Pharaoh, 'To reside in the land have we come, since there is not enough pasture for your servant's flocks, since the famine is heavy in the land of Canaan, and now please grant that your servants should dwell in the Land of Goshen.'"
