Our sedra begins the amazing story of Yakov &
Esav. This is a saga that never really ends; the
progeny of Yakov - we Jews - will go on forever,
& we will be locked in battle, both physical &
spiritual, with Esav’s descendants until the end of time.
The pattern of infertility that we saw with Sara Imenu continues with Rivka. The Gemara says “G-d “desires the prayers & dialogue of the righteous,” & distress - as in this case, when Rivka, like Sara, struggles to get pregnant - is what usually motivates a person to reach out to G-d.
