Bede : Behold, I have given a thousand pieces of silver to your brother; this will be a veil of the eyes to all who are with you, wherever you shall go; and remember that you have been discovered. While speaking playfully, because she herself had said that he was her brother, and he says that she was discovered when by pretending she covered the truth, saying that he who was her husband was her brother, and he encourages her to remember this in the future, lest she should incur the same disgrace by similar pretense henceforth. But if in this reading, where Sarah, with Abraham's permission, is taken by kings, but, with God's provision, is returned to her husband undefiled, it pleases to understand something allegorical, it signifies that the Church is often to be assailed by the temptations of worldly powers, certainly with God permitting, who is called her husband by the gift of heavenly protection and grace, so that being tested by adversities, it may become more evident with what firm faith, with what chastity devoted to God, with what great care of her Creator she is always to be protected from all the snares of enemies, and never corrupted from the simplicity of her faith. However, that the king, in returning Sarah to Abraham, likewise gave sheep and oxen, servants and handmaids, and much money, signifies the time when the kingdom of this world would submit its neck to the Christian faith, and hold in veneration that religion which once it strove to overthrow. That Sarah, being desired and taken by kings twice and yet was never defiled, first indeed as a young woman by Pharaoh, and now of more advanced age by Abimelech, signified that the Church, though always to be troubled by labors in this life, would yet experience two greater persecutions than the rest; one of the Roman Empire, which she endured, as it were, in her youth, and overcame most valiantly and gloriously with the help of the Lord; the other of the Antichrist, which she is to suffer, as it were, in old age, that is, at the impending end of her temporal life, and with the same merciful Lord's help, she is to defeat. For that Sarah was of such great beauty that even in old age she could be loved for her grace of form, signifies that the Church, in that last time, will be adorned with such glory of virtues, that the fierce enemy with his satellites will greatly envy her, and therefore will strive to attack her with all his snares and forces; fulfilling the prophecy where it is said of her sons: They shall still bring forth fruit in old age; they shall be fat and flourishing (Psalms 92:14), that is, that they may steadfastly declare the faith in which they glory among the evils they suffer. That each king was prevented by God's provision from violating Sarah, signifies thus the rage of persecutors, with God's mercy, being restrained, so that none of those who truly belong to the Church can be seduced from the chastity of faith and charity which is in Christ. That each king was compelled by plagues to restore Sarah to her husband and corrected the presumptuous abduction by giving money, signified that the persecutors are often restrained from harming the faithful by adversity and losses of temporal goods; and are to be changed to the reverence or companionship of the same faithful, which we know has happened in persecutions sometimes, and we believe will be eminently so in that last great persecution; and this by the prayers of spiritual leaders, and the indulgence and mercy of the Lord Savior, who has deigned to unite the holy Church to Himself by the bond of matrimony. For both the blessed Abraham, praying for Abimelech, aptly designates both the Lord Savior himself who is at the right hand of God, who also intercedes for us, and the pastors and rulers of the same Church who, since they take care of her chastity, do not neglect to pray to the Lord even for her adversaries that they may not be able to defile her but may cease sooner from harmful undertakings. Nor should it be considered irrelevant that by Abimelech, a good man and fearing God, the persecutors of the good can be symbolized. For it is customary in Scriptures for both evils to be designated through good people and goods through bad people. For even the blessed Pope Gregory did not hesitate to place the most wicked kings Saul and Jehoiachin in the figure of the Lord Savior, and on the contrary, through the faithfulness of Uriah's deed, he says the faithlessness of the Jews is designated. — Commentary on Genesis (Hexaemeron)
