How can I search for everytime the OT talks about God but doesn't use Elohim (but instead uses El, Eloah, etc.)?
- You could do a root search "<Root = lbs/he/אֵל:5> INTERSECTS god" and look at the results in Analysis mode grouping by Hebrew lemma. Then you would get something like this. The Logos Help file describes the Analysis view if you aren't familiar with it. But if this doesn't make sense please advise.
- A search for <Person God> NOT INTERSECTS <Lemma = lbs/he/אֱלֹהִים> is probably too broad with all the pronominal references. You may want to look at the "Referred to As" section of the Factbook entry for God.
