R’ Shimon Shizuri and R’ Shimon say: They did not disagree that concerning anything of one category he is liable. Concerning what do they differ? Concerning something of two categories, that R’ Eliezer holds [him] liable to a chatas, and R’ Yehoshua exempts [him]. Said R’ Yehudah: Even if he intended to pick figs and he picked grapes, [to pick] grapes and he picked figs, [to pick] black ones and he picked white ones, [or to pick] white ones and he picked black ones, R’ Eliezer holds [him] liable to a chatas, and R’ Yehoshua exempts [him]. [But] said R’ Yehudah: I am amazed that R’ Yehoshua exempts [him] in this case. If so, why is it stated (Lev. 4:23): In which he sinned? This is to exclude an unwitting act.
