Genesis 3:1-5    The tempter's subtlety:
We have here an account of the temptation with which Satan assaulted our first parents, to draw them into sin, and which proved fatal to them. Here observe,
I. The tempter, and that was the devil, in the shape and likeness of a serpent.
1. It is certain it was the devil that beguiled Eve. The devil and Satan is the old serpent <Rev. 12:9>, a malignant spirit, by creation an angel of light and an immediate attendant upon God's throne, but by sin become an apostate from his first state and a rebel against God's crown and dignity. Multitudes of the angels fell; but this that attacked our first parents was surely the prince of the devils, the ring-leader in the rebellion: no sooner was he a sinner than he was a Satan, no sooner a traitor than a tempter, as one enraged against God and his glory and envious of man and his happiness. He knew he could not destroy man but by debauching him. Balaam could not curse Israel, but he could tempt Israel, <Rev. 2:14>. The game therefore which Satan had to play was to draw our first parents to sin, and so to separate between them and their God. Thus the devil was, from the beginning, a murderer, and the great mischief-maker. The whole race of mankind had here, as it were, but one neck, and at that Satan struck. The adversary and enemy is that wicked one.
