Joab Could Not Answer the Arameans and Ran to David

Joab was the most feared general in David's army. He had fought Philistines and Ammonites and the men of Edom. He had killed enemies in their beds and rivals in the open gate. He was not a man who ran from a fight.

But the Arameans stopped him with a sentence.

"You are not the son of Jacob." Not a sword. Not a spear. A sentence. And Midrash Tehillim 60:1, compiled as part of the broader Midrash Aggadah tradition, records that when Joab heard this, he did not know what to do or how to answer. He went to David and said, "This and that was said to me by the sons of Aram."

The Arameans had done something subtle and devastating. They had pointed to the moment in Genesis (31:42) when Jacob himself, in his covenant with Laban, called on God as the only witness between them. No human witnesses. Only God. To the Arameans, this was a crack in the lineage. A covenant made with no one watching could be unmade with no one watching. You cannot claim descent from a patriarch who couldn't get a witness to sign the paperwork.

It was a legal argument. An identity argument. And Joab, the killer of kings, had no answer for it.

David convened the Sanhedrin, the high court of Israel, which the Midrash calls by the name "Lilies," drawing on the Song of Songs (7:3): "Your belly is a heap of wheat, encircled with lilies." These wise men were the living repository of everything Israel had inherited and everything it was obligated to pass on. David brought the Aramean challenge to them as a puzzle requiring solution.

The Sanhedrin answered with history. Their forefathers had made not one but two foundational covenants. Abraham had made a covenant with Abimelech (Genesis 21:23), a formal agreement in front of witnesses, binding their descendants. And Jacob had made a covenant with Laban in Aram, which meant that the very people now challenging Joab's lineage were themselves bound to Israel by covenant. The Arameans were arguing from within a relationship they had tried to deny.

Then the Sanhedrin pushed further. When the Philistines had once tried to enter the land, Israel had challenged their right, and the Philistines had claimed they honored the covenant Abraham made with Abimelech. Israel had accepted this. The Deuteronomy passage about the Avvim and Caphtorim (2:23) showed that even distant nations were protected by covenant law. The system was consistent. The Arameans were not outside it. They were inside it, and they had forgotten.

The Sanhedrin added a final point about precedence. When the nations tried to argue that Israel had not arrived first, the counter-evidence was Balaam's own prophecy: "Behold, a people came out of Egypt; behold, they cover the surface of the land, and they are dwelling opposite me" (Numbers 22:5). Even the prophet hired to curse Israel had testified to their prior claim.

Joab returned to the Arameans armed with this. But the Midrash pauses on what happened next, because Joab did something unexpected. He stopped before attacking. He asked himself a question: "If I destroy them now, what will I do when I ascend from the war?" The Midrash lets the question hang without a neat answer. A warrior who had just been given every legal and ancestral justification to destroy his enemies instead chose to think about what destruction would cost.

David named the psalm that the Midrash hangs this story on: "To teach." That is not a musical direction. It is a purpose. The whole encounter, the legal challenge, the genealogical research, the moment of hesitation before the killing blow, was meant to teach something. Perhaps that identity is not a possession but a covenant. Something made with others, binding in both directions, that you have to understand before you can defend.
