But as for you, turn, and journey into: this order is very much like the one in verse 7. The people are to turn back from Kadesh Barnea and return to the wilderness; so New Revised Standard Version “journey back.”

For wilderness see 1.1.

In the direction of the Red Sea: or “on the road to the Red Sea” (compare Good News Translation; see 2.1; Num 14.25). The literal meaning of the name of this body of water seems to be “Sea [or, Lake] of Reeds,” and the Good News Translation footnote at Exo 13.18 provides a brief statement of how it is used:
RED SEA: (in Hebrew literally “Sea of Reeds”) evidently referred to (1) a series of lakes and marshes between the head of the Gulf of Suez and the Mediterranean, the region generally regarded as the site of the events described in Exodus 13, and was also used to designate (2) the Gulf of Suez, and (3) the Gulf of Aqaba.

Most Bibles in English follow the traditional “Red Sea” in all occurrences of the name; Good News Translation has “Red Sea” when the name appears in the context of the exodus from Egypt, and elsewhere “Gulf of Aqaba” (Exo 23.31; Num 14.25; 21.4; Deut 1.40; 2.1; Judges 11.16; 1 Kgs 9.26; 2 Chr 8.17; Jer 49.21) or “Gulf of Suez” (Exo 10.19; Num 33.10; Isa 11.15), as required by the context. Here Moffatt, Good News Translation, Nova Tradução na Linguagem de Hoje, and Traduction œcuménique de la Bible (footnote) have “Gulf of Aqaba”; Bible en français courant, New Jewish Publication Society’s Tanakh, Die Bibel im heutigen Deutsch have “Sea of Reeds.” A translator must decide how this name is to be translated in each instance, whether to try to let the context determine the meaning assigned, or simply to translate by the traditional “Red Sea” in all passages.
