A perforated plant-pot is like the ground. [If] one separated terumah from [produce of] the ground on behalf of [produce of] a per-forated plant-pot, or from [produce of] a perforated plant-pot on behalf of [produce of] the ground, his terumah is terumah. [If he separated terumah] from [produce of] a non-perforated [pot] on behalf of [produce of] a perforated [pot], it is terumah, but he must separate terumah again. [If he separated terumah] from [produce of] a perforated [pot] on behalf of [pro-duce of] a nonperforated [pot], it is terumah, but it may not be eaten until he takes out terumah and tithes for it.

One may tithe from [tevel] of a Jew on behalf of [tevel] of a gentile; from [tevel] of a gentile on behalf of [tevel] of a Jew; from [tevel] of a Jew on behalf of [tevel] of a Cuthean; from [tevel] of a Cuthean on behalf of [tevel] of a Cuthean. R’ Eliezer forbids [tithing] from [tevel] of a Cuthean on behalf of [tevel] of a Cuthean.
