Hapax marks a single occurrence, whether an event, experience, action, or stated future act.

The adverb marks an occurrence as single: a past experience or event, an action performed on one occasion, or a future act stated as occurring one more time. Its contexts may contrast that single occurrence with repetition, as in suffering repeatedly versus appearing on one occasion in Hebrews 9:26, but the supplied verses do not require separate lexical senses.

1. A single occurrence in the stated context · dominant

   The form is tagged as an adverb in every supplied occurrence and marks an event, action, or experience as occurring on one occasion. In 2 Corinthians 11:25 the APB renders a sequence of hardships with “once I was stoned”; in Hebrews 9:7 it renders the high priest’s entry as “only once a year”; and in Hebrews 9:27 it renders the appointed human death as occurring “once.” Other clauses apply the same limitation to being enlightened in Hebrews 6:4, Christ’s appearance in Hebrews 9:26, and a promised shaking “once more” in Hebrews 12:26.

In the Anselm Project Bible: The APB commonly expresses the adverb with “once,” including 2 Corinthians 11:25, Hebrews 6:4, and Hebrews 9:27. In particular contexts it expands the clause as “once a year,” “once more,” or “once for all”; Those expansions reflect the whole clause rather than a fixed rendering of the term alone.
