Acts 7:23-25

7:23 But when he was about forty years old, it entered his mind to visit his fellow countrymen the Israelites. 7:24 When he saw one of them being hurt unfairly, Moses came to his defense and avenged the person who was mistreated by striking down the Egyptian. 7:25 He thought his own people would understand that God was delivering them through him, but they did not understand.
