"Annoncez-le en Égypte, publiez-le à Migdol, publiez-le à Nof et à Tahpanhès, dites: Debout! Tiens-toi prêt! car le glaive dévore autour de toi.
Tze'enah Ure'enah
“Declare in Egypt, proclaim, etc.” [46:14]. Say in Egypt and proclaim in the city of Migdol and in the city of Nof and in the city of Tahpanhes. Say that they should prepare themselves for the war, since the sword will devour all those around you.
Rashi
“Stand fast and prepare yourself” for the war. והכן means “and prepare.”
