With this found I five verses in the KJV and ESV (instead of 4 and 3).
Abraham\b[^?]+\b([Kk]nife|[Ww]ood)\b
Many thanks to Katoog for this post. (And many thanks to JPG for his extensive assistance in private messages).
As JPG knows, I complained with some of our other formulations that I *was* getting hits in the search results, *but* there was no highlighting in those hits. But in Katoog's post above, I now get *both* the hits I'm wanting, *and* the highlighting of the results.
Many thanks to both of you!
