If anyone is too poor to pay the stated amount, he is to present the person to the priest, who will then set the value for him according to what the person making the vow can afford.
He must not exchange or substitute a good one for a bad one, or a bad one for a good one; if he should dishonestly substitute one animal for another, both the original and the substitute become property of the Sanctuary.
"If a man dedicates his house to GOD, into the possession of the Sanctuary, the priest assesses its value, setting it either high or low. Whatever value the priest sets, that's what it is.
"If a man dedicates to GOD part of his family land, its value is to be set according to the amount of seed that is needed for it at the rate of fifty shekels of silver to six bushels of barley seed.
But if he dedicates it after the Jubilee, the priest will compute the value according to the years left until the next Jubilee, reducing the value proportionately.
When the field is released in the Jubilee, it becomes holy to GOD, the possession of the Sanctuary, GOD's field. It goes into the hands of the priests.
the priest will compute its proportionate value in relation to the next year of Jubilee. The man must pay its value on the spot as something that is now holy to GOD, belonging to the Sanctuary.
"No one is allowed to dedicate the firstborn of an animal; the firstborn, as firstborn, already belongs to GOD. No matter if it's cattle or sheep, it already belongs to GOD.
If it's one of the ritually unclean animals, he can buy it back at its assessed value by adding twenty percent to it. If he doesn't redeem it, it is to be sold at its assessed value.
"But nothing that a man irrevocably devotes to GOD from what belongs to him, whether human or animal or family land, may be either sold or bought back. Everything devoted is holy to the highest degree; it's GOD's inalienable property.
He is not permitted to pick out the good from the bad or make a substitution. If he dishonestly makes a substitution, both animals, the original and the substitute, become the possession of the Sanctuary and cannot be redeemed."
