And Abimelech fought against the city all that day; and he took the city, and slew the people that were therein: and he beat down the city, and sowed it with salt.

And Samson said, Let me die with the Philistines. And he bowed himself with all his might; and the house fell upon the lords, and upon all the people that were therein. So the dead that he slew at his death were more than they that he slew in his life.

Then the five men departed, and came to Laish, and saw the people that were therein, how they dwelt in security, after the manner of the Sidonians, quiet and secure; for there was none in the land, possessing authority, that might put them to shame in anything, and they were far from the Sidonians, and had no dealings with any man.

And there was no deliverer, because it was far from Sidon, and they had no dealings with any man; and it was in the valley that lieth by Beth-rehob. And they built the city, and dwelt therein.
