The character of Moses, as presented by the Bible, shows that from his youth he was endowed with a high sense of righteousness and with a warm love for his people. The fact that he was able, without material power, to lead his people for forty years, proves not only his mental vigor, but also his patience and kindness; and yet he earned but little gratitude. Even his brother proved untrustworthy and, with Miriam, intrigued against him; but he was never embittered and is rightly called "meek above all men which were upon the face of the earth." This did not, however, imply any weakness, for he could be stern and inflexible where the honor of his God was at stake. He was a prophet great alike in word and deed, one who saw God not merely in dreams and visions but "face to face." The glory of God was reflected on his countenance so that he was forced to veil it. ...
To what extent the law as existent in the Pentateuch is of Mosaic origin cannot be satisfactorily determined, but Moses may safely be regarded as the originator of the divine ordinances contained therein. It is certain that he was better qualified for this work, both by education and by divine guidance, than any other Israelite.
