“And he looked this way and that way, and when he saw that there was no man, he slew the Egyptian, and hid him in the sand.”
King James Version (KJV)
2:12 He slew the Egyptian - Probably it was one of the Egyptian task - masters, whom he found abusing his Hebrew slave. By special warrant from heaven (which makes not a precedent in ordinary cases) Moses slew the Egyptian, and rescued his oppressed brother. The Jew's tradition is, that he did not slay him with any weapon, but as Peter slew Ananias and Sapphira, with the word of his mouth.
