Leviticus 27:8-10

World English Bible

⁸ But if he is poorer than your valuation, then he shall be set before the priest, and the priest shall assign a value to him. The priest shall assign a value according to his ability to pay.

⁹ “‘If it is an animal of which men offer an offering to Yahweh, all that any man gives of such to Yahweh becomes holy. ¹⁰ He shall not alter it, nor exchange it, a good for a bad, or a bad for a good. If he shall at all exchange animal for animal, then both it and that for which it is exchanged shall be holy.
