slew. If the Egyptian killed the Hebrew, Moses only acted agreeably to the divine law in thus slaying the Egyptian; nor did he violate the law of Egypt; for, according to Diodorus Siculus he who saw a man killed, or violently assaulted on the highway, and did not rescue him, if he could, was punished with death. Moses, therefore, in this transaction, acted as a brave and good man; especially as at this time there was little probability of obtaining justice on an Egyptian murderer.
