We've now learned about Reuben and Simeon from the Twelve Tribes of Israel.

Most of the other twelve were sons of Jacob, but Ephraim was actually the grandson of Jacob.
Because Jacob got mad at one of his other sons Reuben, he said that Ephraim would be brought up to be an equal to the other sons.
