The sons of Levi: Gershon, Kohath, and Merari.

Simeon and Levi are brothers, weapons of violence are their knives! ¹ 

The sons of Leah were Reuben, Jacob’s firstborn, as well as Simeon, Levi, Judah, Issachar, and Zebulun.

She became pregnant again and had another son. She said, “Now this time my husband will show me affection, ¹  because I have given birth to three sons for him.” That is why he was named Levi. ² 

In three days, when they were still in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s brothers, each took his sword ¹  and went to the unsuspecting city ²  and slaughtered every male.

Then Jacob said to Simeon and Levi, “You have brought ruin ¹  on me by making me a foul odor ²  among the inhabitants of the land – among the Canaanites and the Perizzites. I ³  am few in number; they will join forces against me and attack me, and both I and my family will be destroyed!”
