What are the R numbers in the eSword NASB? Psalm 103:14 (NASB)
(14)  For He Himself knows our frame; He is mindful that we are but dust.

Here, He is R2 and but is R3. What do those R numbers that mean? Are they still Hebrew words?



The screenshot was taken from my NASB package in eSword.
Found an answer from a forum question (post #2 by Bradley S. Cobb): NASB + marking's what are they for


  the N stands for footnote. the R stands for cross-reference. the notes/references are in the NASB commentary file.
