What meanest thou by all this drove? He does not inquire as if he were altogether ignorant; seeing he had heard from the servants, that oxen and camels and asses and other cattle were sent him as a present; but for the purpose of refusing the gift offered to him: for when anything does not please us, we are wont to make inquiry as concerning a thing unknown to us. Jacob, however; is urgent; nor does he cease to ask, till he induces his brother to receive the gift: for this was as a pledge of reconciliation. Besides, for the purpose of persuading his brother, he declares, that it would be taken as a great kindness not to refuse what was given. For we do not willingly receive anything but what we certainly know to be offered to us freely and with a ready mind. And because it is not possible that we should willingly honor any but those we love, Jacob says that he rejoiced in the sigh of his brother as if he had seen God or an angel: by which words he means, not only that he truly loved his brother, but also that he held him in esteem. But it may seem, that he does wrong to God, in comparing Him with a reprobate man; and that he speaks falsely, because had the choice been given him, he would have desired nothing more earnestly than to avoid this meeting with his brother. Both these knots are easily untied. It is an accustomed form of speaking among the Hebrews, to call whatever is excellent, divine. And certainly Esau being thus changed, was no obscure figure of the favor of God: so that Jacob might properly say, that he had been exhilarated by that friendly and fraternal reception, as if he had seen God or an angel; that is, as if God had given some sign of his presence. And, indeed, he does not speak feignedly, nor pretend something different from what he has in his mind. For, being himself perfectly free from all hatred, it was his chief wish, to discharge whatever duty he could towards his brother; provided that Esau, in return, would show himself a brother to him.

And he said, what meanest thou by all this drove which I met?.... Not as being ignorant of the design of it; for no doubt the several drovers, according to their instructions from Jacob, had acquainted him with it; but he chose not to take the present on what they said, but was willing to have it from Jacob's own mouth, and that he might have the opportunity of refusing it:
and he said, these are to find grace in the sight of my lord; to gain his favour and good will; and which, as it was a token of Jacob's good will to him, so, by his acceptance of it, he would know that he bore the same to him also. It was usual in the eastern countries to carry presents to friends, and especially to great men, whenever visits were paid, as all travellers in general testify to be still the usage in those parts, to this day.

And he said, These are to find grace in the sight of my lord.
Esau then inquired about the camp that had met him, i.e., the presents of cattle that were sent to meet him, and refused to accept them, until Jacob's urgent persuasion eventually induced him to do so.
