Leviticus 27:32-34 ▼

32 For every tenth part of herd or flock, whatever passes under the rod, the tenth one shall be holy to Yahweh.

33 He shall not inquire whether it is good or bad, nor shall he exchange it; or if he does exchange it, then both it and its substitute shall become holy. It shall not be redeemed.’”

34 These are the commandments which Yahweh commanded Moses for the sons of Israel at Mount Sinai.
