Due to your inquiry, I did some research and I previously did not know about them. Here's what I found:
The Daughters of Shallum (Nehemiah 3:12)
Who they were: Daughters of Shallum, son of Hallohesh, who was the ruler of half the district of Jerusalem.
Their Action: They worked with their father to repair a section of Jerusalem's wall, near the Tower of the Ovens.
Significance: They are the only women listed as contributors to the rebuilding effort in the entire chapter, highlighting their active role in community defense and service.
Sheerah (1 Chronicles 7:24)
Who she was: A granddaughter of Ephraim, noted in a genealogy.
Her Action: She is credited with building the cities of Lower and Upper Beth-horon, and Uzzen-sheerah.
Significance: She's the only woman in the Old Testament named as a city founder, showing significant leadership and building prowess in ancient times.
Key Distinction:
Shallum's daughters were contemporary builders with their father in Nehemiah's time (post-exile), working on the wall.
Sheerah was an ancestral figure from much earlier, noted for founding cities.
Together, they represent women in the Bible who broke traditional molds, taking on roles of responsibility and contributing significantly to their people's welfare and security, whether by fortifying a city or building new ones.
