Genesis 34:25

On the third day , when they were sore , two of the sons of Jacob , Simeon and Levi , Dinah’s brothers , took their swords and came against the city while it felt secure and killed all the males .

Three days later, while all of them were still in pain, two of Jacob`s sons, Simeon and Levi, Dinah`s brothers, took their swords and attacked the unsuspecting city, killing every male.

And it came to pass on the third day, when they were sore, that two of the sons of Jacob, Simeon and Levi, Dinah's brethren, took each man his sword, and came upon the city boldly, and slew all the males.
