This is one of the most startling single verses in the Targum. Pseudo-Jonathan on Genesis 24:55 tells us what happened while everyone was still talking. Bethuel, the father of Rivekah, ate from that same prepared dish — the one he had poisoned for Eliezer — and in the morning the household found him dead.
Read it slowly. The plain Torah text simply says the brother and mother asked Eliezer to let Rivekah stay a little longer. The Targum explains why the father is suddenly missing from the conversation. He had sat down to eat, and the food had remembered whom it was meant for.
The Aramaic tradition is ruthless about this kind of thing. What Proverbs says — "He that diggeth a pit shall fall into it" (Proverbs 26:27) — is not a metaphor at Bethuel's table. It is a menu. The hand that prepared the poison cannot, in the end, distinguish itself from the intended victim.
The brother and the mother adjust quickly. "Let the damsel dwell with us the days of one year or ten months, and then she shall go." A wedding has become a funeral overnight. They are trying to delay. They are trying to keep a daughter close while a house reels.
But Eliezer will refuse the delay in the next verse. His mission was never Bethuel's to extend. The father is gone; the bride's path is open; the servant will not linger while Abraham waits.
The deep lesson: the Accuser's own food feeds the Accuser. When you plot harm under a holy roof, the Torah says, you are preparing your own last supper.
