Deuteronomy 1:40

פנו לכם TURN YE — I thought to let you pass across the breadth of the land of Edom in a northerly direction and thus enter the Land (cf. Rashi on Numbers 34:3); you, however, became degenerate and caused this delay for yourselves. פנו לכם TURN YE backwards, and proceed through the wilderness towards the Red Sea; — for the wilderness through which they were travelling was to the south of Mount Seir separating the Red Sea from Mount Seir. — Now proceed in the direction of the Sea and travel round Mount Seir along the whole of its south side from the west to the east.

וְאַתֶּ֖ם פְּנ֣וּ לָכֶ֑ם וּסְע֥וּ הַמִּדְבָּ֖רָה דֶּ֥רֶךְ יַם־סֽוּף׃

But as for you, turn, and take your journey into the wilderness by the way of the Sea of Suf.
