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 words it stands beside are the nouns, verbs and adjectives immediately before or after it, counted in every verse where the word stands. The article, the conjunctions and the prepositions are left out, because they stand beside every word.

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.
