Leviticus 27:30-33

YLT(i) 30 And all tithe of the land, of the seed of the land, of the fruit of the tree, is Jehovah's—holy to Jehovah. 31 `And if a man really redeem any of his tithe, its fifth he addeth to it. 32 `And all the tithe of the herd and of the flock—all that passeth by under the rod—the tenth is holy to Jehovah; 33 he enquireth not between good and bad, nor doth he change it; and if he really change it—then it hath been—it and its exchange is holy; it is not redeemed.'
