EXTRA · Side-ring · Parashas Shoftim · Passuk 20:01
When you go out to war against your enemies and see horse and chariot, a people more numerous than you, you shall not fear them, for the Eternal your God is with you, who brought you up from the land of Egypt.
Chazal / classical source (beyond TT-numbered main-ring units): Sotah 42a.
Lemma: כִּי ה׳ אֱלֹהֶיךָ עִמָּךְ.
English: ‘For the Eternal your God is with you’ – this is the camp of the Shechinah.
Derash identifying the presence (Bavli) — Hashem’s being “with you” refers to the accompanying Shechinah / Ark.
The reason one must not fear is that Hashem’s presence goes with the army; the memory of the Exodus reinforces that presence.
