What Does Genesis 21:31 Mean?

The naming of the place as Beersheba commemorates the oath sworn by both men at the site. The name itself preserves the memory of the treaty, meaning either 'well of the seven' or 'well of the oath.' The geography of the Negev is now marked by the history of covenant diplomacy.

The naming of locations is a recurring theme in Genesis that links the land to the word of God or the acts of the patriarchs. Beersheba becomes the southern anchor of the Promised Land. The history of the oath is inscribed into the map of the future.

The memorials we leave in the landscape or in language help preserve the truth of our commitments. A name that carries the memory of an oath is a safeguard against the forgetfulness of later generations. Honor is maintained when our history is visible in our names.
