Bechoros 8:9-10

Bechoros 8:9

A firstborn son receives a double share of his father’s property but not of his mother’s property. He also doesn’t receive a double share of the property’s appreciation between the father’s death and the division of property, nor of expected accrual, just of what is currently in possession. Similarly, a woman doesn’t collect the value of her kesubah, nor do daughters collect their maintenance, nor does a man who married his brother’s widow collect the deceased’s property from the estate’s increase in value or expected accrual like they do from what’s actually in possession.

Bechoros 8:10

The following property doesn’t return to its ancestral owners in the Jubilee (yoveil): the extra share received by a firstborn son, what a man inherits from his wife, property inherited by a man who performs yibum (levirate marriage) and gifts; this is the opinion of Rabbi Meir. The Sages say that a gift is the same as a sale (and therefore does revert to its original owners). Rabbi Elazar says that everything goes back in yoveil. Rabbi Yochanan ben Brokah says that a man who inherits (a family cemetery) from his wife gives it back to the members of her family in yoveil, though he may deduct (the value of her plot).
