The Prohibition of Cooking Meat in Milk Learned From a Kid

There we learned: the flesh of a clean animal cooked in the milk of a clean animal is forbidden to cook and forbidden to derive benefit from. From where are these matters derived? Rabbi Eleazar said: Because the verse says, "And Judah sent the kid of the goats" (Genesis 38:20). So, in every place where "kid" is stated without qualification, even a calf or a lamb is implied. And let us learn from it. Another verse is written, "And the skins of the kids of the goats" (Genesis 27:16). Thus they are two verses that come as one, and any two verses that come as one do not teach a general rule. This works well for the one who says they do not teach; but for the one who says they do teach, what is there to say? Two limiting expressions are written.
