The Shofar

(2) All shofars are fit to be blown on Rosh Hashanah, except for that of a cow because it is called a horn and not a shofar. Rabbi Yose said, "But are not all shofars also called a horn, as it is stated (Joshua 6:5), 'upon a long blast from the ram’s horn'?”

(3) The shofar of Rosh Hashanah – is to be from an ibex, and straight. Its mouth is to be coated in gold, and there are to be two trumpets, one on each side of it. The shofar blast is to be long and the trumpet blast is to be short, since the commandment of the day is with a shofar.

(6) If a shofar was cracked and one glued it, it is unfit. If one glued fragments of shofars, it is also unfit. If it was pierced and he sealed the hole; if the hole impedes the blast, it is unfit, but if not, it is fit.

(7) One who blows into a cistern, or into a cellar or into a barrel; if he heard the sound of the shofar, he has fulfilled his obligation; if he heard the sound of an echo, he has not fulfilled his obligation. And so too, he who was passing behind a synagogue, or whose house was adjacent to a synagogue, and heard the sound of a shofar or the sound of someone reading the scroll of Esther, on Purim; if he had intention for the commandment, he has fulfilled his obligation, but if not, he has not fulfilled his obligation. Even though this one heard and that one heard, this one had intention, and that one did not have intention.

(8) A deaf-mute person, or a shoteh, or a minor, cannot relieve others from their obligation for hearing the shofar they blew the shofar for them. This is the general rule: all those who are not obligated to carry out a particular action, cannot release others from their obligation.
