3 But God came to Abimelech in a dream of the night, and said to him, Behold, thou art but a dead man, because of the woman whom thou hast taken. For she is a man's wife. 4 Now Abimelech had not come near her. And he said, Lord, wilt thou slay even a righteous nation? 5 Said he not himself unto me, She is my sister? And she, even she herself said, He is my brother. In the integrity of my heart and the innocency of my hands have I done this. 6 And God said unto him in the dream, Yea, I know that in the integrity of thy heart thou has done this, and I also withheld thee from sinning against me. Therefore suffered I thee not to touch her. 7 Now therefore restore the man's wife. For he is a prophet, and he shall pray for thee, and thou shalt live. And if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine.

(Read Genesis 20:1-8)
Crooked policy will not prosper: it brings ourselves and others into danger. God gives Abimelech notice of his danger of sin, and his danger of death for his sin. Every wilful sinner is a dead man, but Abimelech pleads ignorance. If our consciences witness, that, however we may have been cheated into a snare, we have not knowingly sinned against God, it will be our rejoicing in the day of evil. It is matter of comfort to those who are honest, that God knows their honesty, and will acknowledge it. It is a great mercy to be hindered from committing sin; of this God must have the glory. But if we have ignorantly done wrong, that will not excuse us, if we knowingly persist in it. He that does wrong, whoever he is, prince or peasant, shall certainly receive for the wrong which he has done, unless he repent, and, if possible, make restitution.
