ד יש מקנת כסף שנימול לשמנה ויש יליד בית שנימול ביום שנולד כיצד לקח שפחה ולקח עוברה עמה וילדה הרי זה נימול לשמנה ואף על פי שלקח העובר בפני עצמו והרי העובר עצמו מקנת כסף הואיל וקנה אמו קודם שנולד נימול לשמנה.
4 Under certain circumstances, a slave acquired by purchase is circumcised on the eighth day after birth, while one born in the house is circumcised on the day he is born. For example, a female slave is bought, and her still unborn child is bought at the same time, the child, subsequently born, is circumcised when eight days old. For, although it had been separately bought, and is thus a slave acquired by purchase, still, as the mother had been acquired before the infant's birth, it is circumcised on the eighth day.
