The Targum Pseudo-Jonathan opens the scene of Rebekah's plan with a line the Hebrew does not speak. "Behold, this night those on high praise the Lord of the world, and the treasures of the dew are opened in it" (Genesis 27:6).
According to the Targum, this is leyl shimurim — the watchful night, the same night on which, generations later, Israel will leave Egypt. It is Pesach. The angels are singing. The dew of blessing is descending. And Rebekah knows exactly which son must stand in the room when Isaac opens his mouth to bless.
Why does the Targum place this on Passover?
The rabbis loved to knit the calendar together. In Pseudo-Jonathan's reading, the key nights of Jewish history converge on the same date. The night Jacob receives the blessing is the night Moses will lead the Exodus is the night the final redemption will come. One night carries them all.
The phrase the treasures of the dew are opened is evocative. In Jewish mysticism, dew (tal) is the image of resurrection and of quiet, abundant blessing. Every Pesach morning, in synagogues around the world, Jews add the prayer for dew — Tefillat Tal — to the Amidah. That prayer is rooted, in part, in the Targum's reading of this very night.
Why does this matter for Jacob?
Because the blessing Isaac is about to give is not an ordinary blessing. It is tied to the calendar of redemption itself. Rebekah, who heard the oracle in the womb — the elder shall serve the younger — understands that the door is open tonight and tonight only. She is not stealing a blessing. She is placing the right son under the right sky.
The takeaway: the Targum reminds us that holy timing matters. Some decisions can only be made on certain nights.
