Genesis 27:26

26.Come near now, and kiss me. We know that the practice of kissing was then in use, which many nations retain to this day. Profane men, however, may say, that it is ludicrous for an old man, whose mind was already obtuse, and who moreover had eaten and drunk heartily, should pour forth his benedictions upon a person who was only acting a part. (47) But whereas Moses has previously recorded the oracle of God, by which the adoption was destined for the younger son, it behoves us reverently to contemplate the secret providence of God, towards which profane men pay no respect. Truly Isaac was not so in bondage to the attractions of meat and drink as to be unable, with sobriety of mind, to reflect upon the divine command given unto him, and to undertake in seriousness, and with a certain faith in his own vocation, the very work in which, on account of the infirmity of his flesh, he vacillated and halted. Therefore, we must not form our estimate of this blessing from the external appearance, but from the celestial decree; even as it appeared at length, by the issue, that God neither vainly sported, nor that man rashly proceeded in this affair: and, truly, if the same religion dwells in us which flourished in the patriarch’s heart, nothing will hinder the divine power from shining forth the more clearly in the weakness of man.
