40.5 «Listen, Child. You said: ‘Remember to sanctify feast days. Not only for yourself, but also for your son and your daughter, your servant and your maidservant, even for your horse it is said that they must not work on Sabbaths’. Now tell me: if a hen lays an egg on a Sabbath or a sheep lambs on a Sabbath, will it be legal to use the fruit of its womb, or will it be considered as an opprobrium?»
«I know that many rabbis, Shammai is the last of them and is still alive, say that an egg laid on a Sabbath is against the precept. But I think that there is a difference between man and animals or whoever fulfils a natural act, such as giving birth. If I compel a horse to work I am responsible for its sin, because I force it to work with a whip. But if a hen lays an egg which has matured in its ovary or a sheep lambs a little one on a Sabbath, because it is ready to be born, no, such a deed is not a sin, neither is the egg laid or the lamb born on a Sabbath a sin in the eyes of God.»
«But why, if every kind of work is a sin on Sabbaths?»
«Because to conceive and give birth correspond to the will of the Creator and comply with the laws which He gave to every creature. Now, the hen does nothing but obey the law according to which after so many hours of growth an egg is complete and ready to be laid, and the sheep also obeys the laws laid by Him Who created everything, according to which laws twice a year when springtime is on the meadows in bloom, and when the trees in the forest lose their leaves and men muffle themselves up because of the intense cold, sheep should mate so that later they may give milk, meat and nourishing cheese in the opposite seasons of the year, that is in the months when the toil for the crops is harder or the bleakness is more painful because of frostbite. If therefore a sheep, when its time is up, gives birth to a little lamb, oh! the little lamb can certainly be sacred also on an altar, because it is the fruit of the obedience to the Creator.»
