The association of the Red Sea with the biblical account of the Israelites crossing the Red Sea is ancient, and was made explicit in the Septuagint translation of the Book of Exodus from Hebrew to Koine Greek in approximately the third century B.C. In that version, the "Yam Suph" () is translated as "Erythra Thalassa" (Red Sea). Although reeds do not grow in the Red Sea today (reeds do not grow in salt water), Professor Colin Humphreys explains the discrepancy on the basis that a freshwater marsh of reeds could have existed around Aqaba.
