Genesis 49:3-5

Complete Jewish Bible

³ “Re’uven, you are my firstborn,
my strength, the firstfruits of my manhood.
⁴ Though superior in vigor and power
you are unstable as water, so your superiority will end,
because you climbed into your father’s bed
and defiled it — he climbed onto my concubine’s couch!

⁵ “Shim‘on and Levi are brothers,
related by weapons of violence.
