3 But God came to Abimelech in a dream by night, and said to him, "Indeed you are a dead man because of the woman whom you have taken, for she is a man's wife." 4 But Abimelech had not come near her; and he said, "Lord, will You slay a righteous nation also? 5 Did he not say to me, 'She is my sister'? And she, even she herself said, 'He is my brother.' In the integrity of my heart and innocence of my hands I have done this." 6 And God said to him in a dream, "Yes, I know that you did this in the integrity of your heart. For I also withheld you from sinning against Me; therefore I did not let you touch her. 7 Now therefore, restore the man's wife; for he is a prophet, and he will pray for you and you shall live. But if you do not restore her, know that you shall surely die, you and all who are yours."

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.
