This enhanced version includes Strong’s number marked after each applicable entry in the form of the letter “S”, a space and the Strong’s number in superscript. This means that if you are studying a word in the Strong’s Concordance, you can search this PDF for the Strong’s number preceded by a capital S and a space and find it easily without having to search with Hebrew characters.
This PDF is 3132 pages and is not a scan but an actual text-based document.
