וּבַשָּׁנָה֙ הָרְבִיעִ֔ת יִהְיֶ֖ה כָּל־פִּרְי֑וֹ קֹ֥דֶשׁ הִלּוּלִ֖ים לַיהוָֽה׃
제사년에는 그 모든 과실이 거룩하니 여호와께 드려 찬송할 것이며
Tosefta Demai
A Jewish Priest [can] eat with a Samaritan Priest when [the food is] made in [a state of] impurity, but when [it is] made in [a state of] purity, behold, he does not eat it with him, because he feeds him the meat of an unblemished first-born [calf], and has him drink wine from a [ritually] pure fourth[-year vineyard].*See Deut. 15:22 and Lev. 19:24, and discussions at Bekh. 5:2 (also Bekh. 32b:10) re: first-born calf, and Ter. 3:9 and Y. Peah VII.5.2 re: fourth-year vineyard.
