Leviticus 27:2-13

2“Speak to the sons of Israel and say to them, ‘1When someone makes an explicit vow, he shall be valued according to your assessment of persons belonging to the Lord. 3If your assessment is of a male from twenty years even to sixty years old, then your assessment shall be fifty shekels of silver, by 2the shekel of the sanctuary. 4Or if 3the person is a female, then your assessment shall be thirty shekels. 5And if the person is from five years even to twenty years old, then your assessment for a male shall be twenty shekels, and for a female, ten shekels. 6But if the person is from a month even up to five years old, then your assessment shall be 4five shekels of silver for a male, and for a female your assessment shall be three shekels of silver. 7If the person is from sixty years old and upward, if a male, then your assessment shall be fifteen shekels, and for a female, ten shekels. 8But if he is poorer than your assessment, then he shall be presented before the priest, and the priest shall assess him; 5according to 6the means of the one who vowed, the priest shall assess him.

9‘Now if it is an animal of the kind that 7one can present as an offering to the Lord, any such animal that one gives to the Lord shall be holy. 108He shall not replace it nor exchange it, a good for a bad, or a bad for a good; yet if he does exchange animal for animal, then both it and its substitute shall become holy. 11If, however, it is any unclean animal of the kind which 9one does not present as an offering to the Lord, then he shall place the animal before the priest. 12And the priest shall assess it 10as either good or bad; as you, the priest, assess it, so shall it be. 13But if he should ever want to redeem it, then he shall add a fifth of it to your assessment.
