Talmud sur Kil'ayim 7:6

“Rebbi Jehudah said, when is this? When the ship touches ground.” Rebbi Ḥaggai said, Rebbi Jehudah follows his opinion³⁰In the Babli it is held that if R. Jehudah asks in the Mishnah, when is this?, he does not disagree with the anonymous Tanna but explains the latter’s position (Eruvin 81a–82b, Sanhedrin 24b). This is not the position of the Yerushalmi; cf. Ševi‘it 7, Note 90. since Rebbi Jehudah exempts water³¹Mishnah Beẓah 5:4: “If somebody borrows vessels before the holiday, they follow the feet of the borrower, on the holiday, the feet of the lender. Similarly, if a woman borrowed from another spices, water, or salt, they follow the feet of both of them. Rebbi Jehudah exempts water, for water has no consistency.” If both the borrower and the lender made an eruv (cf. Peah 8, Note 56), the borrowed things can only be moved inside the territory accessible to both of them. R. Jehudah exempts water since it is permitted on a holiday to drink water from a brook; that water was outside the permitted domain when the holiday started., as it has no consistency³²In this interpretation, the water is disregarded and the wooden ship is considered as lying on the gound.. Rebbi Abin said, it is more reasonable to assume his opinion changed; if the ship does not touch ground, would it not be as if the ship touched ground³³According to R. Ḥaggai, the condition that the boat touch ground seems unintelligible.? If the ship does not touch ground, its tithes are of practice; one tithes from it for a flower pot without hole and from a flower pot without hole for it, as it was stated³⁴Kilaim 7:6, Note 84.: “The tithes from a flower pot without hole are of practice³⁵Without any biblical basis. The flower pot is of clay which may be impermeable. Plants growing in a flower pot are considered growing on the ground only if the flower pot has a hole letting the earth in the pot absorb moisture from the ground. A wooden ship touching ground can always be said to be connected to the earth under it; it might only be compared to a flower pot with a hole., its heave does not create dema‘ and one does not owe a fifth for it.” Rebbi Hila in the name of Rebbi Eleazar: If somebody acquires a flower pot with a hole in Syria, even if he did not acquire the earth under it or the ground on which it stands, he acquired it to be obligated for tithes and the Sabbatical, even if it sits on two pegs. Even Rebbi Jehudah will agree with this. What is the difference between this case³⁶The flower pot with a hole permanently fixed on pegs above ground is obligated, the ship anchored but not touching ground is exempt. and that of a ship? A ship rises and falls, this [flower pot] rests in its place.
