v.16
The elders identify the immediate practical crisis: wives must be found for the remaining men because the women of Benjamin are gone.
v.17
They articulate a broader political aim: Benjamin’s survivors must retain an “inheritance,” so a full tribe is not erased from Israel’s tribal order.
v.18
They restate the limiting oath: they cannot give their own daughters as wives to Benjamin, invoking a curse tied to the earlier communal vow.
