Exodus 2:12
looked <06437> [he looked.]
attacked <05221> [slew.]
If the Egyptian killed the Hebrew, Moses only acted agreeably to the divine law (Ge 9:6) in thus slaying the Egyptian; nor did he violate the law of Egypt; for, according to Diodorus Siculus (1. 1. 17), "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.

As the Nile was held sacred by the Egyptians, as well as the animals it contained, to which they annually sacrificed a girl, or as others say, both a boy and girl, God might have designed this plague as a punishment for such idolatry and cruelty; and to shew them the baseness of those elements which they reverenced, and the insufficiency of the gods in which they trusted. All the punishments brought upon them bore a strict analogy to their crimes.
