According to Biblical law, a person survived by his sons and daughters is inherited only by his sons. The Sages, however, instituted that a man stipulate to his wife in her marriage contract (ketubah) that their daughters who survive him be entitled to support from his estate until they marry or reach full maturity.
Admon says, "Because I am male, do I lose?" Rabban Gamliel prefers his opinion, but the final law follows the first authority—the daughters take priority.
