Exodus 14:20

ויבא בין מחנה מצרים AND IT CAME BETWEEN THE CAMP OF EGYPT — A parable: it may be compared to one who is proceeding on a journey, his son walking in front of him. If, now, brigands come to capture him (the son), he takes him away from in front of him and places him behind himself. If a wolf then comes behind him he places him again in front. If brigands come in front of him and wolves behind him, he places him on his arm and fights against them. Thus did God do for Israel, as it says, (Hosea 11:3) “I led Ephraim — He took them upon His arms” (Mekhilta). ויהי הענן והחשך AND THERE WAS CLOUD AND DARKNESS to the Egyptians. ויאר AND IT — the pillar of fire — ILLUMINATED the night for the Israelites, and went before them as was its way to go every night, whilst the darkness of the cloud was turned towards the Egyptians. ולא קרב זה אל זה SO THAT ONE APPROACHED NOT ANOTHER — [This does not mean that one person did not approach another but]: this camp did not approach that camp (Mekhilta).

וַיָּבֹ֞א בֵּ֣ין ׀ מַחֲנֵ֣ה מִצְרַ֗יִם וּבֵין֙ מַחֲנֵ֣ה יִשְׂרָאֵ֔ל וַיְהִ֤י הֶֽעָנָן֙ וְהַחֹ֔שֶׁךְ וַיָּ֖אֶר אֶת־הַלָּ֑יְלָה וְלֹא־קָרַ֥ב זֶ֛ה אֶל־זֶ֖ה כׇּל־הַלָּֽיְלָה׃

and it came between the camp of Miżrayim and the camp of Yisra᾽el; and it was a cloud and darkness to them, but it gave light by night to these: so that the one came not near the other all the night.
