Tosefta על בכורים 1:2

Buying a single tree growing in another person's field exempts the buyer from reciting the confession while presenting the first fruits, according to R. Meir. Sages, however, argue that the individual neither brings the first fruits nor recites the confession. R. Judah insists that all proselytes must present their first fruits but are not obliged to recite the confession. He also refers to Moses' father-in-law and his clan, the Kenites, who are obligated to both bring first fruits and recite the confession, as commanded in Num. 10:32. Disagreeing with R. Meir, R. Yosé argues that priests should present first fruits but should not recite the confession because they did not inherit a portion of the land. He also contends that priests received their portion from the Levites, similar to how Levites received their portion from the Israelites, as detailed in Num. 35:2.
