By traditional corpus
Conventional, traditional groupings — biblical authorship is debated, so this is a traditional corpus grouping, not an authorship claim. Some books belong to more than one corpus (Luke is in both the Gospels and the Lukan corpus, and so on), so these shares overlap and need not total 100%. Each figure is a share of the word’s 1 distinct verse.

How translations render this word
Counts come from each version’s own published word-to-Strong’s tagging or interlinear alignment — an approximate guide to how each version renders this word, not a word-level alignment the data otherwise carries. Because each total is that version’s own tagged count, the per-version totals vary from one another and need not match the appearance or distinct-verse counts above. These counts may also differ from a printed concordance because Lemma counts each distinctly tagged rendering and does not collapse phrase taggings into a single head-word total. This is a fixed set of word-tagged versions (KJV, ASV, BSB, ULT) and does not change with the reading translation you choose elsewhere. Each version’s license is shown beside its name below (and on Sources).

These are occurrences of the same Greek lexeme (G3510) in the Septuagint — not a translation of any one Hebrew word. The store carries no word-level Hebrew↔Greek alignment, so no Hebrew original is asserted here. Counts come from the recovered LXX Strong's tagging — high-frequency vocabulary is well covered, while rare or late forms may be untagged — so they reflect tagged occurrences and may slightly undercount.
