Leviticus 27:8 BBE

⁶  And if the person is from one month to five years old, then the value for a male will be five shekels of silver, and for a female three shekels.

⁷  And for sixty years old and over, for a male the value will be fifteen shekels, and for a female, ten.

⁸  But if he is poorer than the value which you have put on him, then let him be taken to the priest, and the priest will put a value on him, such as it is possible for him to give.

⁹  And if it is a beast of which men make offerings to the Lord, whatever any man gives of such to the Lord will be holy.

¹⁰  It may not be changed in any way, a good given for a bad, or a bad for a good; if one beast is changed for another, the two will be holy.
