כִּי֩ עֲנַ֨ן יְהוָ֤ה עַֽל־הַמִּשְׁכָּן֙ יוֹמָ֔ם וְאֵ֕שׁ תִּהְיֶ֥ה לַ֖יְלָה בּ֑וֹ לְעֵינֵ֥י כָל־בֵּֽית־יִשְׂרָאֵ֖ל בְּכָל־מַסְעֵיהֶֽם׃
낮에는 여호와의 구름이 성막 위에 있고 밤에는 불이 그 구름 가운데 있음을 이스라엘의 온 족속이 그 모든 행하는 길에서 친히 보았더라
Rashi
לעיני כל בית ישראל בכל מסעיהם [THE CLOUD WAS ON THE TABERNACLE] … IN THE SIGHT OF ALL THE HOUSE OF ISRAEL, THROUGHOUT ALL THEIR JOURNEYS — At every מסע which they made (according to Rashi this means: at every station at which they stopped) the cloud rested upon the Tabernacle in the place where they encamped. A place where they encamped is also called מסע (the literal meaning of which is “journey”). Similar is, (Genesis 13:3) “And he went on to his resting places (למסעיו)“ (cf. Rashi on this verse); similar also is, (Numbers 33:1) “These are the מסעי” — “the places of encampment”. Because from the place of encampment they always set out again on a new journey therefore all the different stages of their journeys (including the places where they encamped) are called מסעות.
Rabbeinu Bahya
כי ענן ה' על המשכן יומם ואש תהיה לילה בו, “for the cloud of the Lord would be over the Tabernacle by day, whereas by night fire would be above it.” We would have expected the Torah to write: ענן ה' ביום ואש (ה') תהיה בלילה. Why did the Torah mention the word “fire” in front of the word “night” when describing the presence of heavenly attributes as manifest in connection with the Tabernacle? The reason is that the Torah wanted to use both “day” and “night” as divine attributes, respectively. (The word “day” is an alternate name for the attribute of Mercy, whereas the word “night” is an alternate name for the attribute of Justice).
It is well known that the name of the attribute of Mercy often appears with the letter מ being repeated, such as in the word יומם, [usually translated as “by day.” Ed.] The basic letters in the word לילה are ליל, the letter ה at the end being the allusion to the attribute of Justice which is most active at night.

You know that this attribute had been particularly active at night when it was applied to the firstborn of Egypt (Exodus 12,29). This is part of the mystical dimension of the words used in Scripture. When we read in Joshua 1,8 that G’d told Joshua to be busy with Torah both by day and by night, the wording is והגית בו יומם ולילה instead of והגית בו ביום ובלילה.
