Do you read, speak and understand ancient Koine Greek??? I'm impressed! ;o)
I can read some. Rusty. I refresh myself by reading John’s letters.
When I read Koine (or Attic) I look like Ike preparing D-Day. For Koine, I got me my lexicon(s), my grammars, and my super weapon: Kittel’s 10 volume ditionary of the NT.
Hebrew... kinda the same thing. Lexicon, Grammar, amd Lisowsky’s exhauative concordance.
And coffee.
