Numbers 18:15

Everything that patar (opens) the racham (womb), of all bashar (flesh) which they qarab (come close) to Yahawah (), both of adam (man) and animal shall be yours: nevertheless you shall padah (surely) padah (redeem) the bakawar (firstborn) of adam (man), and you shall padah (redeem) the bakawar (firstborn) of tamaa (unclean) animals.
