Genesis 49:4-6

Young's Literal Translation

⁴ Unstable as water, thou art not abundant; For thou hast gone up thy father's bed; Then thou hast polluted: My couch he went up!

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.
