Leviticus 27:7-9

The Voice

⁷ If the person is 60 years old or older, it is to be 6 ounces for the male and 4 ounces for the female. ⁸ If someone cannot afford these prices, then bring him to stand before the priest, and the priest will assess the situation and value him according to what the person can afford.

⁹ Whenever someone vows to give an animal that is acceptable as an offering to Me, then that animal is sacred and is the property of the sanctuary.
