A shofar blower in Barzel tribe. There was a story about one of the great bird hunters who died and some say that he was a heretic. Rabbi Yossi went to warm himself up with him. He applied some oil to him and massaged him.
Rabbi Yossi asked him, "Why are you rubbing him?" He replied, "Similarly, we wash the utensils in the heavenly fountain before bringing them to the world to come." Rabbi Yossi said, "The problem with that man is not his physical impurity, and I will not defile myself for him." The other man said, "Some craftsmen glue things back together, but it is not written that way; it is written that they shall be broken like a potter's vessel."
Rabbi Yossi said to him, "Regarding a potter's vessel, it has no clear existence until it is fired, and if it breaks, it can be repaired, but after it is fired, its existence is clear, and if it breaks, it cannot be repaired. However, a glass vessel has a clear existence even before it is fired, and if it breaks, it has a cure." The other man said, "Listen to what you say, and what about glass vessels that are made from the blowing of flesh and blood, and if they break, they have a cure?"
Rabbi Yossi replied, "A person who is made from the blowing of the Holy One, blessed be He, as it is said, 'And He breathed into his nostrils the breath of life,' how much more so!" Rabbi Yitzchak said, "It is not written here 'a craftsman's vessel' but rather 'a vessel of a craftsman.' Until it is fired, it can be returned."
