Ibn Ezra on Genesis 21:30/אבן עזרא על בראשית כ״א:ל׳
אלעדה. כמו לעדות ודע כי מלת שבועה עקרה. שבעה, ובמלת "או השבע שבועה" (במדבר ל, ג) אפרשנה:
1A WITNESS. Le-edah means a witness. It should be noted that the word for oath (shevu’ah) comes from the word for seven (shivah).17 comes from shivah, Abraham called the place be’ersheva, rather than be’er shevu’ah. I will elaborate on this point in my comments on the term oh hishavah shevu’ah (or sweareth an oath).18
