The Hebrew noun beer (בְּאֵר) refers to a well, pit, or spring — a dug or natural source of water. It appears over 35 times in the Old Testament, frequently in narratives of the patriarchs where wells are meeting points and covenant markers.
Wells in Scripture are sites of divine encounter, covenant, and calling. At a well, Hagar received God's promise (Genesis 16). At a well, Rebekah was found for Isaac (Genesis 24). At a well, Jacob met Rachel (Genesis 29). At a well, Moses met Zipporah (Exodus 2). In the New Testament, Jesus meets the Samaritan woman at a well (John 4) and offers 'living water.' The well becomes a theological type: the place where the thirsty encounter the God who provides. Beersheba ('well of the oath') memorializes God's covenant faithfulness to Abraham.
