Genesis 26:29

29. As we have not touched thee. An accusing conscience urges them to desire to hold him closely bound unto them; and therefore they require an oath from him that he will not hurt them. For they knew that he might rightfully avenge himself on them for the sufferings he had endured: but they dissemble on this point, and even make a wonderful boast of their own acts of kindness. At first, indeed, the humanity of the king was remarkable, for he not only entertained Isaac with hospitality, but treated him with peculiar honor; yet he by no means continued to act thus to the end. It accords, however, with the common custom of men, to disguise their own faults by whatever artifice or color they can invent. But if we have committed any offense, it rather becomes us ingenuously to confess our fault, than by denying it, to wound still more deeply the minds of those whom we have injured. Nevertheless Isaac, since he had already sufficiently pierced their consciences, does not press them any further. For strangers are not to be treated by us as domestics; but if they do not receive profit, they are to be left to the judgment of God. Therefore, although Isaac does not extort from them a just confession; yet, that he may not be thought inwardly to cherish any hostility towards them, he does not refuse to strike a covenant with them. Thus we learn from his example, that if any have estranged themselves from us, they are not to be repelled when they again offer themselves to us. For if we are commanded to follow after peace, even when it seems to fly from us, it behoves us far less to be repulsive, when our enemies voluntarily seek reconciliation; especially if there be any hope of amendment in future, although true repentance may not yet appear. And he receives them to a feast, not only for the sake of promoting peace, but also for the sake of showing that he, having laid aside all offense, has become their friend.

Thou art now the blessed of the Lord. This is commonly explained to mean that they court his favor by flatteries, just as persons are accustomed to flatter when they ask favor; but I rather think this expression to have been added in a different sense. Isaac had complained of their injuries in having expelled him through envy: they answer, that there was no reason why any particle of grief should remain in his mind, since the Lord had treated him so kindly and so exactly according to his own wish; as if they had said, What dost thou want? Art thou not content with thy present success? Let us grant that we have not discharged the duty of hospitality towards thee; yet the blessing of God abundantly suffices to obliterate the memory of that time. Perhaps, however, by these words, they again assert that they are acting towards him with good faith, because he is under the guardianship of God.
