The bechor receives two shares of the father’s property, but he does not receive two shares of the mother’s property. Neither does he receive two shares of the improvement, nor of what is fit to come as from what is already in his possession. Neither does a woman [collect] her kesubah [from these], nor the daughters for their sustenance, nor the yavam. None of them receives from the improvement, nor of what is fit to come as from what is already in his possession.
