Moses was learned in all the wisdom of the Egyptians. — Better, was trained, or instructed. There is no direct statement to this effect in the history of the Pentateuch, but it was implied in Moses being brought up as the son of Pharaoh’s daughter, and was in harmony with later paraphrases and expansions of the earlier history. The narrative of Josephus (as above) and the references in the New Testament to Jannes and Jambres as the magicians who withstood Moses (2 Timothy 3:8), and to the dispute of Michael and Satan as to his body (Jude 1:9), indicate the wide acceptance of some such half-legendary history. The passage is instructive, (1) as an indirect plea on the part of Stephen, like that afterwards made by Clement of Alexandria (Strom. i. 5, § 28; 6:5, § 42) and Justin (Dial. c. Tryph. c. 1-4), for the recognition of heathen wisdom as an element in the divine education of mankind; (2) as having contributed to fix the attention of the more cultivated and scholarly of the early Christian critics, such as those named, and Origen, and Jerome, and Augustine, on the teaching of Greek poets and philosophers, and having furnished them with a sanction for such studies.
Mighty in words and in deeds. — Josephus (Ant. ii. 10), still following the same traditional history, relates that Moses commanded the Egyptian forces in a campaign against the Ethiopians, and protected them against the serpents that infected the country, by transporting large numbers of the ibis that feeds on serpents. The romance was completed by the marriage of Moses with the daughter of the Ethiopian king who had fallen passionately in love with him. This was possibly a development of the brief statement in Numbers 12:1. The language of Moses (Exodus 4:10), in which he speaks of himself as “not eloquent” and “slow of speech,” seems at first inconsistent with “mighty in words,” but may fairly be regarded as simply the utterance of a true humility shrinking from the burden of a mighty task.
