How to Find All the Words That Appear Just Once in the Bible

Recently a Logos blog post appeared showing how to research a hapax legomenon in the Bible. This Greek phrase literally means “something said only once” and it refers to a word which appears only once in a literary context or an author’s works. The blog correctly points out that numerous hapax legomena occur in the New Testament.

A Logos user then inquired of me:

Using Logos, how do I discover the hapax legomena in the Bible?

It may surprise you that the answer is incredibly simple with the Concordance tool!

  • Choose Tools | Concordance
  • Build a Concordance report for an interlinear Bible such as the ESV (Please be patient. The first time you build a report for an interlinear Bible takes 3-5 minutes) (A)
  • Designate from the drop down list your desired verse range such as New Testament (B)
  • Select from the drop down list Lemma as the reference to search (C)
  • Type in the sidebar in the Count boxes 1 to 1 (D)
  • Select in the sidebar Bible Text in the Field section (E)
  • Notice the results section on the right displaying the Greek lemmas which only appear 1 time in the New Testament! (F)

Of course, you can change the verse range to Old Testament to find the Hebrew lemmas only appearing one time.

For even more fun, change the resource to search to any resource in your library to discover all of the words appearing only 1 time in that book.

The key is to always set the Count to 1 to 1.

You can also attend an upcoming Camp Logos in Tampa, Akron, Minneapolis, or Phoenix for live hands-on training!

  1. Great training as always!

    The email triggered a memory about a query I did once that was interesting. Basically, a Hebrew word is in the manuscript, but it is not translated. However, the translators included an English word that did not have a Hebrew word. I was wondering how we can find this type of situation. Unfortunately, I do not remember the verse where this occurred.

  2. Sorry, but what the heck is hapax legomena?

    Why don’t we make it easier for the regular logos user and use something we can all understand?

    Thank you,

    • Well, you might have overlooked the sentence behind the first mention of “hapax legomenon” (it reads: “This Greek phrase literally means “something said only once” and it refers to a word which appears only once in a literary context or an author’s works.”)

    Can you create a visual filter from this?

  4. Greg Lawhorn says

    Hi Morris, Camp alumni here.

    Is there a way to use the results to highlight each of those words in the text (I have a lot of highlight styles that reveal features such as singular/plural pronouns, verb tenses, etc).

  5. The word “hapax legomena” describes Hebrew/Greek words that are only used one time in the scripture.

    Thank you for clarifying this.

    Rev. Proctor,
    Is there any way to *save* the Concordance indexing created for a particular version of the Bible…so that it doesn’t have to rebuild itself each time we want to use that particular tool?
    Thanks a million!
