Dunbar uses Moses as being being a prophet from when he lead the Israelites out of Egypt. He talks about about how there will be a Moses that is coming for them to set them free in line 73 and 81-82 of The Ante-Bellum Sermon. He relates the Moses and the Pharaoh in the bible to them and the masters. He says that the Pharaoh believed in slavery in line 53 which would be the masters in their case.
