The Hebrew that is translated as “Lord of hosts” in English (or: “Yahweh of Armies” [translation by John Goldingay, 2018]) is translated in various ways: It’s translated as “God the Highest Ruler” in Kankanaey, as “Lord Almighty” in Newari, as Mndewa Imulungu or “Lord with all power” in Kutu (source: Pioneer Bible Translators, project-specific translation notes in Paratext), as Wànjūnzhī Yēhéhuá (万军之耶和华) or “Jehovah of 10,000 [=all] armies” in Mandarin Chinese, as “Yawe God of the universe” in Mandinka, and in the German (Luther) Bible the second part of the name is transliterated: Herr Zebaoth or “Lord Zebaoth” (Swedish, Finnish and Latvian use the same translation strategy).
The traditional French translation of l’Eternel/Yahve/le Seigneur/Seigneur des armées (“Lord of the armies”) presents a problem when listened to, as Jean-Marc Babut explains (in The Bible Translator 1985. p. 411ff. ):
“For the hearer, the traditional translation l’Eternel/Yahve/le Seigneur des armées can easily be taken in a bad sense: there is nothing, in fact, to prevent the listener from hearing l’Eternel désarmé, ‘the Eternal One disarmed’ or ‘stripped of his power’! (…). Thus the Bible en français courant [publ. 1997] has decided to use the expression Seigneur/Dieu de l’univers, “Lord/God of the Universe”. This formula, which has an undeniably liturgical ring, seems to have been favorably received by users.”
Other, later French Bibles who have chosen a similar strategy, include Parole de Vie (publ. 2017) with Seigneur de l’univers or Bible Segond 21 (publ. 2007) with l’Eternel, le maître de l’univers.
