'Swords' in the Bible

Now on the third day [after the circumcision], when all the men were [terribly] sore and in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s [full] brothers, took their swords, boldly entered the city [without anyone suspecting them of evil intent], and they killed every male.

“Simeon and Levi are brothers [equally headstrong, deceitful, vindictive, and cruel];Their swords are weapons of violence and revenge.
