Rashi on Genesis 27:9/רש"י על בראשית כ״ז:ט׳

1וקח לי AND TAKE FOR ME — (The words may mean “Take that which belongs to me”) — these are mine and not the proceeds of theft. Isaac had made provision in her marriage contract that she should receive daily two kids of the goats (Genesis Rabbah 65:14).

2שני גדיי עזים TWO KIDS OF THE GOATS — Did then two kids of the goats form a meal for Isaac? But the explanation is: it being Passover he offered one as his Paschal sacrifice and of the other he prepared the savoury food. So is it stated in Pirkei DeRabbi Eliezer 32).

3כאשר אהב SUCH AS HE LOVETH (Genesis 27:5) — For the taste of a kid is similar to the taste of a deer.
