The Hebrew place name Be'er Sheva means either 'well of the oath' or 'well of seven' (both sheva). It is one of the most significant cities in the patriarchal narratives — the southernmost city of the Promised Land, marking the southern boundary ('from Dan to Beersheba').
Beersheba is where Abraham planted a tamarisk tree and called on the name of the LORD (Genesis 21:33), where Isaac received covenant confirmation (Genesis 26:24-25), and where Jacob had his vision before descending to Egypt (Genesis 46:1-4). It is a center of covenant renewal across generations. The phrase 'from Dan to Beersheba' marks the full extent of God's promised land — north to south — testifying to the completeness of His covenant gift to Israel.
