🔼The name Hilen in the Bible
The name Hilen occurs only once in the Bible. It's the name of a city located in the territory of Judah, which was given to the priestly sons of Aaron (1 Chronicles 6:58). The Chronicler lists Hilen in close proximity of Debir, and the author of the Book of Joshua mentions a place called Holon, also close to Debir of Judah (Joshua 15:51), which was also given to the sons of Aaron (Joshua 21:15). Scholars generally assume that Hilen and Holon are the same place.
🔼Etymology of the name Hilen
The name Hilen either comes from the verb חול I (hul I), or rather its derived noun חול (hol), meaning sand. Or it comes from the noun חיל (hayil), meaning might, from the verb חול II (hul II), meaning to endure or be firm:
The letter ן (nun) upon which our name ends could be regarded as a predecessor of the common waw-nun couple that personifies or localizes a root idea. The name Hilen would thus mean Sandy Place or Mighty Place.
For a meaning of the name Hilen, NOBSE Study Bible Name List apparently goes with the verb חול II (hul II), meaning to endure or be firm and reads Strong Place. Alfred Jones (Dictionary of Old Testament Proper Names) derives it from חול (hol), meaning sand and proposes Sandy. BDB Theological Dictionary does not interpret our name but lists it under the root חול I (hul I), which would favor the interpretation of Alfred Jones.
