Talmud su Salmi 119:109

It is related of Joseph [the son of] Pisḳas⁵¹Cf. j.Nazir VII, 1, 55d. The text here is corrupt and the reading of GRA which agrees with the Talmud is followed. who had a swelling on his foot that a doctor came to remove it. He said to him, ‘When you have left as much as a single hair, tell me’. He cut the abscess, and when he had left only as much as a single hair,⁵²i.e. the swelling was hanging from the foot as by a hair. he informed him. He called his son Neḥunia and said to him, ‘My son, until now it was your duty to attend to me, but now go your way; for the Sages said, “One must not defile himself for a limb that was severed from a living person, even if it be his father’s” ’.⁵³Joseph was a kohen. When the Sages heard of it they said, ‘Of such a man as he it has been stated, My soul is continually in my hand; yet have I not forgotten Thy law;⁵⁴Ps. 119, 109. [and it further states,] There is a righteous man that perisheth in his righteousness⁵⁵Although Joseph was in danger of dying under the operation, he remembered to warn his son of the law of defilement which devolved upon a kohen. and there is a wicked man that prolongeth his life in his evil-doing.’⁵⁶Eccl. 7, 15.
