This verse is almost identical with 20.16. See there for comments. As the footnotes in Revised Standard Version and other versions indicate, the Hebrew text has “a foreign woman,” where the Vulgate and 20.16 have “foreigners.” Hebrew Old Testament Text Project rates the Hebrew text as “B”; a good number of versions, however, follow Revised Standard Version with “foreigners” or “persons unknown” (New Jerusalem Bible).
