The moment Jacob hesitates is the moment Rebekah makes her most astonishing offer. "If with blessings he bless thee, they shall be upon thee and upon thy sons; and if with curses he should curse thee, they shall be upon me and upon my soul" (Genesis 27:13).
The Targum Pseudo-Jonathan preserves the full weight of her pledge. She is not just saying don't worry, I'll figure it out. She is saying put the curse in my account. Whatever storm falls on you, I will stand in it.
A mother's guarantee
The rabbis read this verse as one of the great acts of maternal faith in the Torah. Rebekah has heard the oracle in her womb — the elder shall serve the younger (Genesis 25:23). She knows, with prophetic certainty, that Jacob is the son of the covenant. And she is willing to absorb every possible curse to make the covenant reach him.
Pseudo-Jonathan's Aramaic doubles the pledge: upon me and upon my soul. It is not enough to say on me. She binds it to her nefesh — her very life. The Targum is telling us that Rebekah's love of Jacob is rooted in a conviction deeper than comfort. She believes the blessing must reach him, and she is willing to stake her eternity to make it so.
The takeaway
Jewish tradition is full of mothers who moved history — Sarah, Rebekah, Rachel, Leah, Yocheved, Miriam, Hannah. Pseudo-Jonathan here gives us Rebekah at her most fierce. She knows the stakes. She knows the cost. And when her son hesitates, she does not reassure him with platitudes. She guarantees the loss with her own soul. That is what covenant faith looks like at 2 a.m. in a tent on Pesach night.
