These are occurrences of the same Greek lexeme (G80) 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.
