Exodus 2:11-13

One day, after Moses had grown up, he went out to where his own people were and watched them at their hard labor. He saw an Egyptian beating a Hebrew, one of his own people. Looking this way and that and seeing no one, he killed the Egyptian and hid him in the sand. The next day he went out and saw two Hebrews fighting. He asked the one in the wrong, “Why are you hitting your fellow Hebrew?”
