[With respect to] date honey, Rabbi Eliezer says [that one is] liable in tithes. Said Rabbi Natan, Rabbi Eliezer agrees that [one is] exempt from tithes, but Rabbi Eliezer [nevertheless] would not eat from [date] honey until the dates had been tithed. Rabbi Eliezer agrees that if the dates were tithed, or [if they] were made into honey in Spain (beAspamya), they are permitted. [Furthermore, with respect to] date honey, Rabbi Eliezer holds that it imparts impurity due to it being a liquid. What did they disagree on? About one who put [date honey] inside water, Rabbi Eliezer hold that [any mixture of date honey and impure water] imparts impurity, but the Sages say, we follow after the majority (i.e., if the impure water is in greater proportion than the date honey, it can impart impurity).
