Rabh of Diphthi has taught, as follows: It is written: "Ye shall fast on the ninth." Do we fast on the ninth? We fast on the tenth. This comes to teach, that he who eats and drinks on the ninth, the verse makes him equal (in merit) to him who would fast the ninth and the tenth.]
"If he has eaten food not fit for eating." Rabha said: If he has chewed pepper or ginger during the Day of Atonement, he is not culpable. The rabbis taught: If he has eaten leaves of reeds he is guiltless; but twigs of vines, he is guilty. What is meant by twigs of vines? Said R. Itz'hak of Magdala: Those that flourish between the first day of the year and the Day of Atonement. R. Kahna says: All the thirty days. We have learned in a Boraitha, as R. Itz'hak of Magdala has said: If he has eaten leaves of reeds he is guiltless; of twigs of vines, he is guilty. What are twigs of vines? Such as flourish between the beginning of the year and the Day of Atonement.
"If he has drunk … brine as fish-lye." How if he has drunk vinegar? He is guilty? We must say our Mishna is according to Rabbi in a Boraitha which says vinegar refreshes a man.

GEMARA: If it is stated "two years," one is understood? Said R. Hisda: It presents no difficulty. The one applies to a healthy child; the other, to a weakly child. R. Huna said: When the child is eight or nine years old, it may be accustomed to fast some hours. When it becomes ten or eleven years old, it may be made to fast rabbinically the whole day. A girl must fast biblically at the age of twelve. R. Na'hman, however, said: When nine or ten years old—some hours; at eleven or twelve—rabbinically the whole day; at thirteen—biblically, a boy. R. Johanan says: So long as it is rabbinical, they need not fast the entire day. Only at ten or eleven they must be habituated to
