This geographic designation appears in Deuteronomy's opening verse, helping locate where Moses delivered his final addresses. The text places Israel 'opposite Suph,' though the exact location remains debated. Some scholars connect it to Yam Suph (the Red Sea or Sea of Reeds), suggesting the phrase originally read 'from the Sea of Reeds.' Ancient versions support this interpretation, with the Septuagint reading 'near the Red Sea.' The ambiguity reflects the challenge of preserving precise geographic memory across generations, especially for wilderness locations that may have lacked permanent settlements.
