Where it leads

How the numbers are counted

Every count on this page comes from STEP Bible's tagged Hebrew and Greek text, the same text the ledger prints. A use is counted once each time the tagging marks a word with this key.

Spellings are counted as the Greek text spells them, with the sentence's own punctuation taken off the word first, so a form that ends a clause is not counted as a second spelling.

The family is read from the lexicon by the stem the two words share, with the accents off, and a person or a place named on the stem is left out.
