(5) In the integrity of my heart . . . --Not only does Abimelech assert this, but Elohim (see Genesis 20:6) admits the plea. And yet this Philistine king indulges in polygamy, and claims the right of taking the female relatives of any one passing through his territory to add them to his harem. But the words mean no more than that he was not consciously violating any of his own rules of morality, and thus illustrate the Gospel principle that men will be punished not by an absolute decree, but equitably, according to their knowledge (Luke 12:47-48). Abimelech was doing wrong, and was suffering punishment, but the punishment was remedial, and for his advancement in right-knowing and right-doing. It is thus by means of revelation that men have attained to a proper understanding of the moral law. Though often called "the law of Nature," yet Nature does not give it, but only acknowledges it when given. The inner light is but a faint and inconstant glimmering, but Christ is the true light; for only by Him does the law of Nature become a clear-rule for human guidance (John 1:9; Romans 2:14-15; Matthew 6:23).
Verse 5. - Said he not unto me, She is my sister? and she, even she herself said, He is my brother. From which it is clear that the Philistine monarch, equally with the Egyptian Pharaoh, shrank from the sin of adultery. In the integrity of my heart and innocency of my hands have I done this.I.e. he assumes the right of kings to take unmarried persons into their harems,
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.
Said he not unto me, she is my sister?.... By this it appears, that Abimelech had a personal conversation with Abraham, and inquired of him about Sarah, who she was, and what relation she was to him, who told him that she was his sister; and for the truth of this he appeals to the omniscient God, who knew that Abraham had told him this:
and she, even she herself said, he is my brother; when Sarah was asked what relation she stood in to Abraham, and he to her, she declared he was her brother; so that Abimelech had reason to conclude, from what both of them had said, that this was the truth of the matter, and especially from what Sarah said, who he thought might be depended on, and would speak out the whole truth on such an occasion:
in the integrity of my heart, and innocency of my hands, have I done this; hereby declaring, that his design was not to defile the woman, and to gratify his lust, but to take her to be his wife; and this he thought to be no evil, though he had a wife, Genesis 20:17; polygamy not being reckoned a sin in those times; and that he had used no violence in taking her, they both seemingly agreeing to it.
