עקידת יצחק — ויחי יעקב בארץ מצרים שבע עשרה שנה

Q — Why does the Torah count Yaakov's seventeen years in Egypt separately before summing his whole life? Why are his best years his last, in exile? Why bless each son distinctly rather than uniformly?

A — A man's true years are measured by the life of avodas Hashem within them, not by mere duration. The seventeen Egyptian years are set apart because, freed of struggle and surrounded by his family's spiritual flourishing, they were Yaakov's fullest living — exile notwithstanding. The differentiated blessings reflect that each tribe carries a distinct portion in building Israel; Yaakov assigns each its fitting role, completing the pattern that spiritual maalos pass by fitness, ranking Ephraim before Menasheh and channeling kingship through Yehudah.
