Genesis 26:8

8. Abimelech, king of the Philistines, looked out at a window. Truly admirable is the kind forbearance of God, in not only condescending to pardon the twofold fault of his servant, but in stretching forth his hand, and in wonderfully averting, by the application of a speedy remedy, the evil which he would have brought upon himself. God did not suffer — what twice had occurred to Abraham — that his wife should be torn from his bosom; but stirred up a heathen king, mildly, and without occasioning him any trouble, to correct his folly. But although God sets before us such an example of his kindness, that the faithful, if at any time they may have fallen, may confidently hope to find him gentle and propitious; yet we must beware of self-security, when we observe, that the holy woman who was, at that time, the only mother of the Church on earth, was exempted from dishonor, by a special privilege. Meanwhile, we may conjecture, from the judgment of Abimelech, how holy and pure had been the conduct of Isaac, on whom not even a suspicion of evil could fall; and further, how much greater integrity flourished in that age than in our own. For why does he not condemn Isaac as one guilty of fornication, since it was probable that some crime was concealed, when he disingenuously obtruded the name of sister, and tacitly denied her to be his wife? And therefore I have no doubt that his religion, and the integrity of his life, availed to defend his character. By this example we are taught so to cultivate righteousness in our whole life, that men may not be able to suspect anything wicked or dishonorable respecting us; for there is nothing which will more completely vindicate us from every mark of infamy than a life passed in modesty and temperance. We must, however, add, what I have also before alluded to, that lusts were not, at that time, so commonly and so profusely indulged, as to cause an unfavourable suspicion to enter into the mind of the king concerning a sojourner of honest character. Wherefore, he easily persuades himself that Rebekah was a wife and not a harlot. The chastity of that age is further proved from this, that Abimelech takes the familiar sporting of Isaac with Rebekah as an evidence of their marriage. For Moses does not speak about marital intercourse, but about some too free movement, which was a proof of either dissolute exuberance or conjugal love. But now licentiousness has so broken through all bounds, that husbands are compelled to hear in silence of the dissolute conduct of their wives with strangers.
