And if [a man] sanctify unto the Lord a field which he hath bought,.... With his own money, of some person in poverty and distress, who was obliged to sell it, and which, according to a former law, returned to the original proprietor in the year of jubilee:which [is] not of the fields of his possession; which he has not by inheritance from his fathers.
Jarchi observes, there is a difference between a field bought, and a field possessed; for a field bought is not divided to the priests in the year of jubilee, because a man cannot sanctify it but until the year of jubilee; for in the year of jubilee it would go out of his hands, and return to the owner; wherefore if he comes to redeem it, he must redeem it with the price fixed for the field of possession: the Jewish doctors are divided about a field bought of a father by a son, whether it is a field of purchase or of possession .
