Leviticus 27:8-10

New Revised Standard Version Updated Edition

⁸ If any cannot afford the equivalent, they shall be brought before the priest and the priest shall assess them; the priest shall assess them according to what each one making a vow can afford.^(A)

⁹ “If the vow concerns an animal that may be brought as an offering to the Lord, any such animal that may be given to the Lord shall be holy. ¹⁰ Another shall not be exchanged or substituted for it, either good for bad or bad for good, and if one animal is substituted for another, both that one and its substitute shall be holy.
