But if he has no desire to get it back, or if he has given it for a price to another man, it may not be got back again.

and if he do not redeem the field, or if he hath sold the field to another man, it is not redeemed any more;

And if he will not redeem it, but it be sold to any other man, he that vowed it, may not redeem it any more.

but if he do not redeem the field, or if he sell the field to another man, it cannot be redeemed any more;
