TSK · Genesis 29:33

Then Rachel said,“God has vindicated me. He has responded to my prayer and given me a son.” That is why she named him Dan.

Then Leah said,“God has granted me a reward because I gave my servant to my husband as a wife.” So she named him Issachar.

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.

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

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