Leviticus 27:26

“Sanctify to Me every firstborn, the first offspring of every womb among the sons of Israel, both of man and beast; it belongs to Me.”

and you shall devote to Yahweh the first offspring of every womb and the first offspring of every beast that you own; the males belong to Yahweh.

“For all the firstborn are Mine; on the day that I struck down all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, from man to beast. They shall be Mine; I am Yahweh.”

“Every devoted thing in Israel shall be yours.
