משנה על שביעית 1:4

Rabbi Judah said: “If so, why do they record the opinion of a single person among the many to set it aside? So that if a man shall say, ‘Thus have I received the tradition’, it may be said to him, ‘According to the [refuted] opinion of that individual did you hear it.’”

An aris which projects from a terrace: Rabbi Eliezer ben Jacob says: if a person standing on [level] ground is able to harvest all of it, [such an aris] prohibits [sowing seed in] four cubits of the field, but if [he is] not [able to do so], it prohibits [sowing seed] only [in] the [soil] which is directly below it. Rabbi Eliezer says: even one who has planted one [row of vines] on the ground, and one on a terrace, then if it is ten handbreadths above the [level] ground, one does not combine with the other; if it is not [ten handbreadths high] then one does combine with the other.
