We know exactly the kind of education that Paul would receive. When he was six years old he would go to school for the first time. Once he had learned to read he would be given little rolls of parchment with certain scripture passages on them, which he would have to learn by heart. The passages were: Deuteronomy 6.4-9; Psalms 113-118; Genesis 1-5; Leviticus 1-8
