8 So Abimelech arose early in the morning and called all his servants and told all these things in their hearing; and the men were greatly frightened. 9 Then Abimelech called Abraham and said to him, “What have you done to us? And how have I sinned against you, that you have brought on me and on my kingdom a great sin? You have done to me things that ought not to be done.” 10 And Abimelech said to Abraham, “What have you encountered, that you have done this thing?” 11 Abraham said, “Because I thought, surely there is no fear of God in this place, and they will kill me because of my wife. 12 “Besides, she actually is my sister, the daughter of my father, but not the daughter of my mother, and she became my wife; 13 and it came about, when God caused me to wander from my father’s house, that I said to her, `This is the kindness which you will show to me: everywhere we go, say of me, “He is my brother.”‘” 14 Abimelech then took sheep and oxen and male and female servants, and gave them to Abraham, and restored his wife Sarah to him. 15 Abimelech said, “Behold, my land is before you; settle wherever you please.” 16 To Sarah he said, “Behold, I have given your brother a thousand pieces of silver; behold, it is your vindication before all who are with you, and before all men you are cleared.” 17 Abraham prayed to God, and God healed Abimelech and his wife and his maids, so that they bore children. 18 For the LORD had closed fast all the wombs of the household of Abimelech because of Sarah, Abraham’s wife.
Abraham tries to justify what he did here. First, he gives the excuse that he didn’t think anyone would fear God in the area except his family. Fair enough, Abraham has seen enough evil in the world to expect that those who fear God are few and far between. Then he tells Abimelech, that Sarah actually is his sister. Well, she is his half-sister. I don’t know how many times I’ve heard, “A half truth is still a lie.” Abraham should have known that as well, and this is horrible justification for his omission of the facts. Both times that he did this, it caused horrible things to happen to the men who took his wife mistakenly. Had he been honest, and trusted God to take care of him, things would have turned out a bit different.
