"We've got to stay together and maintain unity. You know, whenever Pharaoh wanted to prolong the period of slavery in Egypt, he had a favorite, favorite formula for doing it. What was that? He kept the slaves fighting among themselves. But whenever the slaves get together, something happens in Pharaoh's court, and he cannot hold the slaves in slavery. When the slaves get together, that's the beginning of getting out of slavery."

--Martin Luther King, "I've Been to the Mountaintop" (1968)

Dr. King found inspiration for his own struggle in the Biblical Exodus from Egypt. Like the Rashi's interpretation of Moses, he saw disunity as being an obstacle which had to be overcome to achieve true freedom. The Torah also highlights the value of unity prior to redemption in Exodus 2:23, 4:29-31.
