'Set Apart' in the Bible

but the field, when it goes out in the jubilee, shall be holy to LORD, as a field set apart; the possession of it shall be the priest's.

Notwithstanding, nothing set apart, that a man shall set apart to LORD of all that he has, whether of man or beast, or of the field of his possession, shall be sold or redeemed; everything set apart is most holy to LORD.

No one set apart, who shall be set apart from among men, shall be ransomed; he shall surely be put to death.
