Logos 4: Automatically Search the Septuagint for a Greek Word

mp|seminars Tips

Today’s post is from Morris Proctor, certified and authorized trainer for Logos Bible Software. Morris has trained thousands of Logos users at his two-day Camp Logos training seminars.

Several people have recently asked me for an easy way to search the Septuagint (Greek translation of the Hebrew Old Testament) for every occurrence of a Greek lemma.

Here’s one way to do just that:

  • Open an English Bible with a Reverse Interlinear option—such as the ESV—to a New Testament passage
  • Right click on a word
  • From the right menu select Lemma “your word
  • Select Bible Word Study
  • When the Bible Word Study report opens, notice the section Septuagint Translation containing the translation ring
  • Click the Greek word in the center of the ring to see very occurrence of that Greek lemma in the Septuagint!

    This method only provides hits within the 39 books of the Hebrew Bible, so it doesn’t actually return every occurrence in the Septuagint.
    If instead of looking at the Septuagint Translation wheel, you just scroll down to ‘Textual Searches’ and select LXX there, you’ll be able to get every occurrence of the lexical form – assuming that the lemmas are spelled the same between the LXX and the NT. The software is expecting an exact match here, so a lemma like Ἑβραϊστί wouldn’t match Εβραϊστί on account of the LXX not having a breathing mark.

    Dear Vincent Setterholm,
    Thanks for your suggestion. However when I tried it I found that there is no LXX section under the “textual search”, as I only found some English translation versions of the bible like ESV, RSV, etc.
    Do I need to do something to enable LXX?
    Thanks in advance.

  3. I follow the instructions and do not see the LXX come up as an option. Must I choose it as a preferred Bible?
    Thank you.
