Exodus 2:11-15 New Revised Standard Version, Anglicised (NRSVA)
Moses Flees to Midian
11 One day, after Moses had grown up, he went out to his people and saw their forced labour. He saw an Egyptian beating a Hebrew, one of his kinsfolk. 12 He looked this way and that, and seeing no one he killed the Egyptian and hid him in the sand. 13 When he went out the next day, he saw two Hebrews fighting; and he said to the one who was in the wrong, ‘Why do you strike your fellow Hebrew?’ 14 He answered, ‘Who made you a ruler and judge over us? Do you mean to kill me as you killed the Egyptian?’ Then Moses was afraid and thought, ‘Surely the thing is known.’ 15 When Pharaoh heard of it, he sought to kill Moses.
But Moses fled from Pharaoh. He settled in the land of Midian, and sat down by a well.
