Reference: Suph
Easton
(De 1:1, R.V.; marg., "some ancient versions have the Red Sea," as in the A.V.). Some identify it with Suphah (Nu 21:14, marg., A.V.) as probably the name of a place. Others identify it with es-Sufah = Maaleh-acrabbim (Jos 15:3), and others again with Zuph (1Sa 9:5). It is most probable, however, that, in accordance with the ancient versions, this word is to be regarded as simply an abbreviation of Yam-suph, i.e., the "Red Sea."

A place-name in De 1:1 'In the Arabah over against Suph'; AV reads 'over against the Red Sea,' in which case it has been assumed that the word for 'Sea' had fallen out in the received Hebrew text. Suph means 'weeds,' and the 'Sea of Weeds' was the Hebrew name of the Red Sea. The AV is almost certainly correct; the expression was so understood also by Septuagint and Vulgate. It is evident that by the 'Red Sea' the Gulf of 'Akabah is meant, as in Nu 21:4 and elsewhere.
