And the Lord said furthermore unto him,.... Continued his discourse, and gave him another sign:put now thine hand into thy bosom. And he put his hand into his bosom; within his coat, under that part of the garment next to his breast:and when he took it out, behold, his hand [was] leprous as snow; that is, white as snow, as the Targums of Onkelos and Jonathan, through the leprosy that was upon it; it was a leprosy of the white sort, and which is reckoned the worst and most difficult to be cured, see Le 13:3.
It is highly probable that this gave rise to the story told by several Heathen writers, as Manetho , Lysimachus , Trogus , and Tacitus , that Moses and the Israelites were drove out of Egypt by the advice of an oracle, because they had the leprosy, itch, and other impure diseases upon them.
