Genesis 33:5

5.And he lifted up his eyes. Moses relates the conversation held between the brothers. And as Esau had testified his fraternal affection by tears and embraces, there is no doubt that he inquires after the children in a spirit of congratulation. The answer of Jacob breathes piety as well as modesty; for when he replies, that his numerous seed had been given him by God, he acknowledges and confesses that children are not so produced by nature as to subvert the truth of the declaration, that the fruit of the womb is a reward and gift of God. And truly, since the fecundity of brute animals is the gift of God, how much more is this the case with men, who are created after his own image. Let parents then learn to consider, and to celebrate the singular kindness of God, in their offspring. It is the language of modesty, when Jacob calls himself the servant of his brother. Here again it is proper to recall to memory what I have lately touched upon, that the holy man caught at nothing either of earthly advantage or honor in the birthright; because the hidden grace of God was abundantly sufficient for him, until the appointed time of manifestation. And it becomes us also, according to his example, while we sojourn in this world, to depend upon the word of the Lord; that we may not deem it wearisome, to be held wrapped in the shadow of death, until our real life be manifested. For although apparently our condition is miserable and accursed, yet the Lord blesses us with his word; and, on this account only, pronounces us happy, because he owns us as sons.
