When Joseph and Benjamin finally embrace, their tears do not flow for the reasons we expect. Targum Pseudo-Jonathan reads the verse as prophecy.
"He bowed himself upon his brother Benjamin's neck, and wept; because it would be that the house of holiness should be builded in the portion of Benjamin, and be twice destroyed: and Benjamin wept upon Joseph's neck, because he saw that the tabernacle of Shiloh would be in the portion of Joseph and be destroyed" (Genesis 45:14).
Joseph is not weeping only for the brother in his arms. He is weeping for the Beit ha-Mikdash, the Holy Temple, which will one day stand on Mount Moriah — territory assigned to the tribe of Benjamin. That Temple will be destroyed twice: by Babylon in 586 BCE and by Rome in 70 CE. Joseph, in the Targum's mystical reading, is granted a flash of prophetic vision. He sees the two destructions in his brother's neck and weeps.
And Benjamin weeps back. He sees, in his tears on Joseph's neck, the mishkan Shiloh, the Tabernacle of Shiloh, which will stand for 369 years in the territory of Joseph's son Ephraim. That sanctuary will also fall, destroyed by the Philistines around 1050 BCE when the Ark is captured (1 Samuel 4).
The Targum turns a private reunion into a cosmic accounting. Every Jewish sanctuary that will ever stand is in these two brothers' tribal inheritance. Every Jewish sanctuary that will ever fall is in these two brothers' tears. The sages teach that the weeping of tzaddikim — the righteous — is never only about their moment. It reaches forward and backward across generations.
Two brothers cry on each other's shoulders. Two holy houses cry with them. The Jewish tradition of lament begins here, in the arms of the first brothers who learn how to weep for a future they cannot prevent.
