Genesis 49:5-7

Young's Literal Translation

⁵ Simeon and Levi [are] brethren! Instruments of violence -- their espousals!

⁶ Into their secret, come not, O my soul! Unto their assembly be not united, O mine honour; For in their anger they slew a man, And in their self-will eradicated a prince.

⁷ Cursed [is] their anger, for [it is] fierce, And their wrath, for [it is] sharp; I divide them in Jacob, And I scatter them in Israel.
