Genesis 34:25

34:25 In three days, when they were still in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s brothers, each took his sword and went to the unsuspecting city and slaughtered every male.

Genesis 49:5-7

49:5 Simeon and Levi are brothers,

weapons of violence are their knives!

49:6 O my soul, do not come into their council,

do not be united to their assembly, my heart,

for in their anger they have killed men,

and for pleasure they have hamstrung oxen.

49:7 Cursed be their anger, for it was fierce,

and their fury, for it was cruel.

I will divide them in Jacob,

and scatter them in Israel!

Jude 1:22-23

1:22 And have mercy on those who waver; 1:23 save others by snatching them out of the fire; have mercy on others, coupled with a fear of God, hating even the clothes stained by the flesh.
