The name and location of Salim are attested as early as the Septuagint translation of Genesis 33:18, which is confirmed by Jubilees 30:1 and Judith 4:4. The continuity of name and location is clear in a medieval Samaritan chronicle. See Elkan N. Adler, “Une nouvelle chronique samaritaine,” Revue des Etudes Juives 44 (1902), pp. 207, 212. The references are discussed by M.E. Boismard, “Aenon près de Salem (Jean, iii, 23),” Revue Biblique 80 (1973), pp. 219–221.
