7 Now therefore restore the man his wife; for he is a prophet, and he shall pray for thee, and thou shalt live: and if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine. 9 Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done. 10 And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing? 11 And Abraham said, Because I thought, Surely the fear of God is not in this place; and they will slay me for my wife’s sake. 12 And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
God tells Abimelech what he must do to remove the threat of destruction from his house, and when Abimelech awakens the next day he quickly follows through. He doesn’t hold back in expressing his frustration with Abraham, though. “Thou hast done deeds that ought not to be done!”
And now Abraham is frank and forthcoming. “I thought the fear of God is not in this place.” He also admits the exact nature of his relationship to Sarah, yes her husband, but also that he actually is her half-brother.
At last Abimelech and Abraham are having a real and honest communication. Abimelech expresses his genuine offense and Abraham discloses his genuine fears, and now at last the two men are seeing each other honestly. It may not be the happiest of conversations, but their understanding of one another is now in harmony with the truth, which is the only foundation that a real relationship can be built on. Assumptions and unspoken fears lead to relationships that are not congruent with reality, and that disparity always causes harm.
