Exodus 2:13-15

2:13 When he went out the next day, there were two Hebrew men fighting. So he said to the one who was in the wrong, “Why are you attacking your fellow Hebrew?”

2:14 The man replied, “Who made you a ruler and a judge over us? Are you planning to kill me like you killed that Egyptian?” Then Moses was afraid, thinking, “Surely what I did has become known.” 2:15 When Pharaoh heard about this event, he sought to kill Moses. So Moses fled from Pharaoh and settled in the land of Midian, and he settled by a certain well.
