Exodus 1:1-2, 10

Now these are the names of the sons of Israel, who came into Egypt (every man and his household came with Jacob): Reuben, Simeon, Levi, and Judah

Come, let’s deal wisely with them, lest they multiply, and it happen that when any war breaks out, they also join themselves to our enemies and fight against us, and escape out of the land.”
