Leviticus 27:32-34 ▼

32 And all the tithe of the herd and of the flock—all that passes by under the rod—the tenth is holy to YHWH;

33 he does not inquire between good and bad, nor does he exchange it; and if he really exchanges it, then it has been [holy] and its exchange is holy; it is not redeemed.”

34 These [are] the commands which YHWH has commanded Moses for the sons of Israel in Mount Sinai.
