I did a word search on the word GK lemma οἰκτιρμός for "mercy" in Rom 12:1. When I expand the LXX translation section of the word search, it shows 37 occurences, however the circle chart only shows a total 31. רחם has 28 of 37 times, תחנון has 2 of 37 times, and חנן has 1 of 37 time, for a total only 31 rather than 37. So we are missing 6 somewhere.
What's going on?
