Leviticus 27:21; Leviticus 27:28-0

21 When the field is released in the Jubilee, it will become holy, like a field devoted to the LORD; it will become the property of the priests.
28 " 'But nothing that a man owns and devotes to the LORD--whether man or animal or family land--may be sold or redeemed; everything so devoted is most holy to the LORD. 29 " 'No person devoted to destruction may be ransomed; he must be put to death. 30 " 'A tithe of everything from the land, whether grain from the soil or fruit from the trees, belongs to the LORD; it is holy to the LORD. 31 If a man redeems any of his tithe, he must add a fifth of the value to it. 32 The entire tithe of the herd and flock--every tenth animal that passes under the shepherd's rod--will be holy to the LORD. 33 He must not pick out the good from the bad or make any substitution. If he does make a substitution, both the animal and its substitute become holy and cannot be redeemed.' " 34 These are the commands the LORD gave Moses on Mount Sinai for the Israelites.
