"a scroll of 'krithuth'": something that cuts off completely — whence it is ruled: If one says to his wife: Here is your get on condition that you never again go to your father's house; on condition that you never again drink wine — this is not krithuth (in that there is no stage in which complete severance is effected.) (If he says:) on condition that you do not go to your father's house until thirty days from now; on condition that you do not drink wine, until thirty days from now — it is krithuth. If one divorces his wife and says "You are permitted to everyone except so-and-so" — R. Eliezer permits it and the sages forbid it. After the death of R. Eliezer, four elders entered to dispute his words: R. Tarfon, R. Yossi Haglili, R. Elazar b. Azaryah, and R. Akiva.
