Leviticus 27:30-34

ECB(i) 30 And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, becomes to Yah Veh - holy to Yah Veh. 31 And if in redeeming, he redeems of his tithes, he adds the fifth. 32 And all the tithe of the oxen and of the flock, - whatever passes under the scion, the tenth becomes holy to Yah Veh. 33 He neither searches whether good or evil, nor exchanges: and if in exchanging, he exchanges it, then both it and the exchange become holy; - not redeemed. 34 These are the misvoth, Yah Veh misvahed Mosheh for the sons of Yisra El in mount Sinay.
