Exodus 1:1-2, 10

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

Come, let us deal wisely with them, lest they multiply, and it come to pass that when any war breaks out, they also join our enemies, and fight against us, and escape from the land.”
