Language evolves and causes confusion even for what should be the easy words. When measuring something do we use a rule or a ruler? Originally if one wanted to begin measuring from the exact edge a rule was used because the marking began from the edge. if you desired a more precise measure a ruler was used and the beginning mark was not the edge of the instrument but a beginning mark was established very near the edge. Yes this gets complicated to explain because today we simply use the words interchangeably. When using the Bible as a standard of measure, we always begin with the fist verse, In the Beginning… Never should we begin measuring from the middle.
