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.
All Commentaries on Exodus 2:12 Go To Exodus 2
Augustine of Hippo
AD 430
Concerning Moses’ deed, when he killed the Egyptian to defend his brethren, we have treated the point adequately in the book that we wrote against Faustus on the lives of the patriarchs. The question was whether his role in that deed was praiseworthy, insofar as he admitted his sin, just as the richness of the earth, even before useful seeds are planted, is often praised for a growth of plants, even if they are useless. Or perhaps the deed itself should be justified. But to do so does not seem right, for up to that point Moses had no legitimate authority—neither authority that he received from God nor authority ordained by human society. But still, as Stephen says in the Acts of the Apostles, Moses thought that his brethren understood that God would bring them salvation through him, so that by this testimony it appeared that Moses could dare to do this because he was already called by God to act. (But Scripture is silent on this point.)
