Or HaChaim on Genesis 27:27/אור החיים על בראשית כ״ז:כ״ז

1 ויברכהו ויאמר ראה He blessed him saying: "re-ey." This word does not mean "see!" as usual, but is connected to the word ראוי, suitable, worthy. Isaac meant that it was fitting that the fragrance of his son should reflect the fragrance of the fields which themselves enjoyed G'd's blessings.
