Resh Lakish said: This proves that precepts require intention, [for] since he does not eat it the stage when bitter herbs are compulsory, he eats it with [the blessing,] ‘Who createst the fruit of the ground,’ and perhaps he did not intend [to fulfil the obligation of] bitter herbs; therefore he must dip it again with the express purpose of [eating] bitter herbs. For if you should think [that] precepts do not require intention, why two dippings: surely he has [already] dipped it once? But whence [does this food]? Perhaps after a precepts do not require intention, and as to what you argue, why two dippings, [the answer is,] that there may be a distinction for [the sake of] the children. And should you say, if so, we should be informed about other vegetables: If we were informed about other vegetables I would say: Only where other vegetables [are eaten first] do we require two dippings, but lettuce alone does not require two dippings: hence he informs us that even lettuce [alone] requires two dippings, so that there may be a distinction [shown] therewith for the children. Moreover, it was taught: If he ate them [the bitter herbs] while demai, he has discharged [his duty]; if he ate them without intention, he has discharged [his duty]; if he ate them, in half quantities, he has discharged [his duty], providing that he does not wait between one eating and the next more than is required for the eating of half [a loaf]? -it is [dependent on] Tannaim. For it was taught, R. Jose said: Though he has [already] dipped the lettuce [hazereth], it is a religious requirement to bring lettuce and haroseth and two dishes before him. Yet still, whence [does this food]: perhaps R. Jose holds [that] precepts do not require intention and the reason that we require two dippings is that there may be a distinction [shown] for the children?- If so, what is the ‘religious requirement?’ What are the two dishes?-Said R. Huna: Beet and rice. Raba used to be particular for beet and rice, since it had [thus] issued from the mouth of R. Huna. R. Ashi said: From R. Huna you may infer that none pay heed to the following [ruling] of R. Johanan b. Nuri. For it was taught, R. Johanan b. Nuri said: Rice is a species of corn and kareth is incurred for [eating it in] its leavened state, and a man discharges his duty with it on Passover. Hezekiah said: Even a fish and the egg on it. R. Joseph said: Two kinds of meat are necessary, one in memory of the Passover-offering and the second in memory of the hagigah. Rabina said: Even a bone and [its] broth. It is obvious that where other vegetables are present, he recites the blessing, ‘who createst the fruit of the ground’ over the other vegetables and eats, and then recites the blessing, ‘[Who hast commanded us] concerning the eating of bitter herbs,’ and eats. But what if he has lettuce only? Said R. Huna: First he recites a blessing over the bitter herbs, ‘Who createst the fruit of the ground,’ and eats, and then [later] he recites over it ‘concerning the eating of bitter herbs’ and eats.ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗ
