Around 100 BC, Simeon ben Shetach standardized the format of the Ketubah, a Jewish marriage contract that outlines the husband's obligations to his wife. This formalization was significant in safeguarding women's financial rights in the event of divorce, reflecting the evolving social dynamics within Jewish communities. The Ketubah remains an important cultural and religious document, symbolizing the commitment and responsibilities inherent in marriage.

The formalization of the Jewish ketubah format created a unique genre of legal-religious poetry that preserved vows through centuries. This tradition influenced Jewish poets, allowing them to explore themes of love, commitment, and cultural identity in their works.
