[If] one ate [bread] of demai, or [of] first tithe whose terumah has been taken, or [of] second tithe or consecrated produce that were redeemed, or [if] an attendant who ate an olive’s volume, or a Cuthean — the collective blessing is recited on their account. But if one ate tevel, or first tithe whose terumah had not been taken, or [of] second tithe or consecrated pro-duce that was not redeemed, or [if] an attendant ate less than an olive’s volume, or a gentile — the collective blessing is not recited on their account.

R’ Akiva says: Even if one ate a cooked vegetable and it is his sustenance, he recites after it the Three Blessings. One who drinks water to [quench] his thirst says [the blessing of] ‘‘. . . that every-thing came into being through His word.’’ R’ Tarfon says: [He says the blessing of] ‘‘. . . Who creates numerous living things . . . .’’
