לָכֵ֗ן הִנֵּ֤ה אָֽנֹכִי֙ מְפַתֶּ֔יהָ וְהֹֽלַכְתִּ֖יהָ הַמִּדְבָּ֑ר וְדִבַּרְתִּ֖י עַל לִבָּֽהּ׃
אָבער זע, איך רעד זי איבער, און װעל זי אַװעקפֿירן אין מדבר, און װעל רעדן צו איר האַרצן.
Rashi
the wilderness of the peoples That is the wilderness through which they [the children of Israel] traveled for forty years, and so did Hosea prophesy (2:16): “and I will...lead her into the desert.” That is the desert of Sihon and Og. Ezekiel called it the wilderness of the peoples because many nations bordered upon it.
