דֶּגֶל (degel) — flag; (historically) military regiment

Etymology

The word דֶּגֶל is one of the most semantically traveled words in Hebrew. Its modern meaning of "flag" is actually a medieval reinterpretation of an ancient Semitic root whose original meaning remains uncertain — and certainly did not refer to a piece of colored cloth.

The root ד.ג.ל appears across many Semitic languages, pointing to great antiquity; the word's segolate noun pattern (דֶּגֶל, original form dagl-u) further confirms its ancient pedigree. The earliest attestation is not in Hebrew but in Assyrian, where the root means "to look at" or "to observe." An Assyrian inscription describes a deity as "the diglu [the one gazed upon] of the whole world." A related usage survives in the Hebrew Bible's Song of Songs: "He brought me to the banqueting house, and his banner (diglo) over me was love" (2:4) — where the root likely means to gaze with admiration. This same meaning underlies the adjective דָּגוּל ("outstanding, eminent"), also from Song of Songs: "My beloved is radiant and ruddy, dagul [distinguished/gazed upon] among ten thousand" (5:10).

In Syriac (a form of Aramaic), the root ד.ג.ל means "to lie/deceive" — covering over the truth. The same usage appears in Hebrew, as in the Midrash Shir HaShirim Rabbah: "even those deceptions (diggulim) with which Jacob deceived his father." Arabic has the cognate root ج.ذ.ل with meanings spanning "to cover/disguise," "to gild/coat," and also to denote a large group of people (dagghalat = a large company of soldiers). The Arab lexicographer Ibn Manzur explained this last sense through the metaphor: "the ground is hidden beneath the great mass of people."

In Biblical Hebrew, the dominant meaning of דֶּגֶל is "military unit" or "regiment." Nearly every occurrence in the Bible appears in Numbers, where it consistently describes military contingents: "The Israelites shall camp, each in his own division (diglo), under the standards of their ancestral house" (Numbers 1:52). Post-biblical Jewish literature — including the Dead Sea Scrolls (War of the Sons of Light Against the Sons of Darkness: "the first degel carries spear and shield..."), texts from the Jewish military colony at Elephantine (Yeb) in Egypt, and the Talmud — all continue this military usage.

The semantic shift from "regiment" to "flag" was initiated in the early 11th century by the grammarian and lexicographer Jonah ibn Janah in his Sefer HaShorashim (Book of Roots). Ibn Janah tried to reconcile the use of ד.ג.ל in Song of Songs with its use in Numbers, and concluded that the military divisions in Numbers were named after the banners they rallied around — a case of metonymy, the group named for its symbol. He wrote: "Its meaning is of elevation and publicity, like the elevation of a banner and its being known." Rashi, a contemporary of Ibn Janah, still glossed דֶּגֶל as "division/regiment." But later lexicographers and commentators — including David Kimhi (Radak) — began using the word in its modern sense, in parallel with the growing use of flags in medieval Europe, a tradition that had arrived from the Arab world.

• Dead Sea Scrolls period: Continues as "military unit" in War Scroll and related texts
• Early 11th century: Jonah ibn Janah proposes the "flag" interpretation as a metonymy
• 11th–12th centuries: Rashi still glosses as "regiment"; Radak and later authorities adopt "flag" meaning
