Leviticus 27:6-8

New Century Version

⁶ The price for a baby boy one month to five years old is about two ounces of silver; for a baby girl the price is about one and one-half ounces of silver. ⁷ The price for a man sixty years old or older is about six ounces of silver; for a woman it is about four ounces of silver.

⁸ “‘If anyone is too poor to pay the price, bring him to the priest, and the priest will set the price. The priest will decide how much money the person making the vow can afford to pay.
