start with a brief history of Abraham Lincoln. Perhaps do so ambiguously so people do not know you are talking about lincoln until you decide to do so.
Talk about his unexpected role. How people who knew him discounted him. Talk about being left by his family even from a young age.
then move on to begin an analysis of part of Moses’ live
Talk about the mistakes they made and the complications of their legacy but that we should remember them not for their mistakes but instead remember them because of what they were willing and able to do.
Did lincoln really support the slaves. Did Moses mean to disrepsect God.
