Leviticus 27:8-10

Wycliffe Bible

⁸ If it is a poor man, and [he] may not yield the value, he shall stand before the priest, and as much as the priest appraiseth, and seeth that the poor man may yield, so much he shall give (that much he shall give).

⁹ Soothly if any man avoweth a beast, that may be offered to the Lord, it shall be holy,

¹⁰ and it shall not be able to be changed, that is, neither a better for a worse, neither an evil for a good; and if he changeth it, both that, that is changed, and that, for which it is changed, shall be hallowed to the Lord. (and he shall not be able to exchange it for another, that is, neither a better for a worse, nor a bad one for a good one; and if he exchangeth it, both that, which is exchanged, and that, for which it is exchanged, shall be holy to the Lord.)
