Genesis 20:6

And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me; therefore suffered I thee not to touch her. The Lord accepted the excuse of Abimelech, incidentally telling him, however, that the sickness which had prevented the king from consummating the supposed marriage had been inflicted from above, to prevent a greater wrong from being committed. Thus the Lord makes use even of misery and tribulation to keep His children from sin and transgression.
