Exodus 2:11-15 NKJV
Now it came to pass in those days, when Moses was grown, that he went out to his brethren and looked at their burdens. And he saw an Egyptian beating a Hebrew, one of his brethren. So he looked this way and that way, and when he saw no one, he killed the Egyptian and hid him in the sand. And when he went out the second day, behold, two Hebrew men were fighting, and he said to the one who did the wrong, “Why are you striking your companion?”
Then he said, “Who made you a prince and a judge over us? Do you intend to kill me as you killed the Egyptian?”
So Moses feared and said, “Surely this thing is known!” When Pharaoh heard of this matter, he sought to kill Moses. But Moses fled from the face of Pharaoh and dwelt in the land of Midian; and he sat down by a well.
