Genesis 34:25

That young man operation hurt a lot. And 3 days later, all the men in Shekem’s mob still felt really weak. Then 2 of Jacob’s sons, they got some long knives, and they went to attack Shekem’s mob. Those 2 sons were Simeon and Levi, and they were Dinah’s brothers. Nobody in Shekem’s mob knew that Dinah’s brothers wanted to attack them, so they were not ready to fight. Simeon and Levi went into the town, and they killed all the boys and men there.
