declared that as Isaac had been eager for his food (for, as reports, Isaac loved Esau because Esau brought Isaac venison), so Jacob was eager for his food (and thus was headed to Egypt to avoid the famine). The other explained that as Isaac had distinguished between his sons (as reports, loving Esau more than Jacob), so Jacob would distinguish among his sons (going to Egypt for Joseph's account alone). But then Jacob noted on reconsideration that Isaac was responsible for only one soul, whereas Jacob was responsible for 70 souls. Rabbi Judan said that Jacob declared that Isaac blessed him with five blessings, and God correspondingly appeared five times to Jacob and blessed him (in , , , , and ).
