Response: Respectful, what you wrote (and others, including Jewish sources) is somewhat inaccurate. Actually, as I have ben taught and learned, it refers to the “plain meaning of the text” or “literal meaning of the text.” There is a real difference [nuance] between “meaning” versus “interpretation”.
“surface” (“straight”) or the literal (direct) meaning…
(Gen. 1,2) And the earth was empty (tohu) and formless (bohu).
Rashi - The Hebrew word ‘tohu’ means astonishment in English and the word ‘bohu’ means emptiness and next to emptiness. Thus the phrase is ‘amazement and desolation’. This means that a person would be amazed and astonished at anything that was there.
