Levítico 22, 29-23

And when ye will offer a sacrifice of thanksgiving unto the LORD, offer it at your own will. So Abraham returned unto his young men, and they rose up and went together to Beer-sheba; and Abraham dwelt at Beer-sheba. Only the firstling of the beasts, which should be the LORD's firstling, no man shall sanctify it; whether it be ox, or sheep: it is the LORD's. Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the LORD. For they are wholly given unto me from among the children of Israel; instead of such as open every womb, even instead of the firstborn of all the children of Israel, have I taken them unto me. And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
