Targum Pseudo-Jonathan on (Genesis 14:15) turns Abram's night raid into a double operation with a prophetic shadow.
The Aramaic says Abram divided his forces in the night: a part were to engage with the kings, and a part were hidden to smite the firstborn of Egypt. This is the Targumist's telescopic vision at full stretch. The night battle in which Abram defeats the four kings is being linked, across centuries, to the night of the tenth plague in (Exodus 12:29), when the firstborn of Egypt will die. One part of Abram's company, in this reading, is detached for a task that will not actually occur for four hundred years. The division of forces is both tactical and prophetic.
And then the Targum drops an extraordinary phrase about where Abram pursued his enemies: unto (the place) of the memorial of sin which was to be in Dan. The Aramaic is remembering that Dan — the northern city where Abram stopped chasing the kings — is the same Dan where Jeroboam, first king of the northern kingdom, will set up one of his two golden calves (1 Kings 12:29). The Targumist is marking the ground.
The patriarch who rescues his nephew stops at the exact latitude where, generations later, his descendants will erect idolatry. Geography becomes moral memory. Abram's farthest northern reach is the place his people will farthest fall.
This is Targum Pseudo-Jonathan's peculiar gift. A single night's raid becomes a map of Jewish history — from Abram's rescue to the Exodus to the schism of the kingdoms. The ground remembers everything that will happen on it. When Abram halts at Dan, heaven remembers what Dan will become.
