Testament of Judah 7
Judah recounts a military campaign in which he and Dan disguise themselves as Amorites to infiltrate a hostile city, then open the gates to their brethren by night — a stratagem of concealment preceding a sudden overthrow. Three walls are cast down, the hostile kings' refuge at Thamna is assaulted, and Judah sustains injury in the breach. Dan's timely aid turns the tide. The kings ultimately petition Jacob, who makes peace and restores all captives. Judah then builds Thamna; Jacob builds Rhambael. Judah notes he was twenty years old, and the Canaanites feared him and his brothers.
1
And the next day it was told us that the cities of the two kings with a great host were coming against us. I therefore and Dan feigned ourselves to be Amorites, and went as allies into their city. And in the depth of night our brethren came, and we opened to them the gates; and we destroyed all the men and their substance, and we took for a prey all that was theirs, and their three walls we cast down. And we drew near to Thamna, where was all the refuge of the hostile kings. Then having received hurt I was wroth, and charged upon them to the brow of the hill; and they slang at me with stones and darts; and had not Dan my brother aided me, they would have been able to slay me. We came upon them therefore with wrath, and they all fled; and passing by another way, they besought my father, and he made peace with them, and we did to them no hurt, but made a truce with them, and restored to them all the captives. And I built Thamna, and my father built Rhambael. I was twenty years old when this war befell, and the Canaanites feared me and my brethren.
