2 Now Abraham said of Sarah his wife, "She is my sister." And Abimelech king of Gerar sent and took Sarah.
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."
8 So Abimelech rose early in the morning, called all his servants, and told all these things in their hearing; and the men were very much afraid. 9 And Abimelech called Abraham and said to him, "What have you done to us? How have I offended you, that you have brought on me and on my kingdom a great sin? You have done deeds to me that ought not to be done." 10 Then Abimelech said to Abraham, "What did you have in view, that you have done this thing?" 11 And Abraham said, "Because I thought, surely the fear of God is not in this place; and they will kill me on account of my wife. 12 But indeed she is truly my sister. She is the daughter of my father, but not the daughter of my mother; and she became my wife. 13 And it came to pass, when God caused me to wander from my father's house, that I said to her, 'This is your kindness that you should do for me: in every place, wherever we go, say of me, "He is my brother." ' "
14 Then Abimelech took sheep, oxen, and male and female servants, and gave them to Abraham; and he restored Sarah his wife to him. 15 And Abimelech said, "See, my land is before you; dwell where it pleases you." 16 Then to Sarah he said, "Behold, I have given your brother a thousand pieces of silver; indeed this vindicates you before all who are with you and before everybody." Thus she was rebuked. 17 So Abraham prayed to God; and God healed Abimelech, his wife, and his female servants. Then they bore children; 18 for the Lord had closed up all the wombs of the house of Abimelech because of Sarah, Abraham's wife.

Commentary on Genesis 20:1-8
(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.
Commentary on Genesis 20:9-13
(Read Genesis 20:9-13)
See here much to blame, even in the father of the faithful. Mark his distrust of God, his undue care about life, his intent to deceive. He also threw temptation in the way of others, caused affliction to them, exposed himself and Sarah to just rebukes, and yet attempted an excuse. These things are written for our warning, not for us to imitate. Even Abraham hath not whereof to glory. He cannot be justified by his works, but must be indebted for justification, to that righteousness which is upon all and unto all them that believe. We must not condemn all as hypocrites who fall into sin, if they do not continue in it. But let the unhumbled and impenitent take heed that they do not sin on, thinking that grace may abound. Abimelech, being warned of God, takes the warning; and being truly afraid of sin and its consequences, he rose early to pursue the directions given him.
Commentary on Genesis 20:14-18
(Read Genesis 20:14-18)
We often trouble ourselves, and even are led into temptation and sin, by groundless suspicions; and find the fear of God where we expected it not. Agreements to deceive generally end in shame and sorrow; and restraints from sin, though by suffering, should be thankfully acknowledged. Though the Lord rebuke, yet he will pardon and deliver his people, and he will give them favour in the sight of those with whom they sojourn; and overrule their infirmities, when they are humbled for them, so that they shall prove useful to themselves and others.
