"And the Lord said furthermore unto him, 'Put now thine hand into thy bosom.' And he put his hand into his bosom; and when he took it out, behold his hand was leprous as snow. And He said, 'Put thine hand into thy bosom again.' And he put his hand into his bosom again, and plucked it out of his bosom; and, behold, it was turned again as his other flesh." The leprous hand and the cleansing thereof present to us the moral effect of sin, as also the way in which sin has been met in the perfect work of Christ. The clean hand, placed in the bosom, becomes leprous; and the leprous hand, placed there, becomes clean. Leprosy is the well-known type of sin; and sin came in by the first man and was put away by the second. "By man came death, by man came also the resurrection of the dead." (1 Cor. xv. 21.) Man brought in ruin, man brought in redemption; man brought in guilt, man brought in pardon; man brought in sin, man brought in righteousness; man filled the scene with death, man abolished death and filled the scene with life, righteousness, and glory. Thus, not only shall the serpent himself be eternally defeated and confounded, but every trace of his abominable work shall be eradicated and wiped away by the atoning sacrifice of Him "who was manifested that He might destroy the works of the devil." "And it shall come to pass, if they will not believe also these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land; and the water which thou takest out of the river shall become blood upon the dry land." This was a solemn and most expressive figure of the consequence of refusing to bow to the divine testimony. This sign was only to be wrought in the event of their refusing the other two. It was first to be a sign to Israel, and afterwards a plague upon Egypt. (Comp. chapter vii. 17.)
