1. Beyond human comprehension or reach · dominant

   In Judges 13:18, the masculine singular adjective describes the name asked about; the APB renders the clause, "seeing it is incomprehensible?" In Psalm 139:6, feminine singular forms describe knowledge as too far beyond the speaker, which the APB renders "too incomprehensible for me" and "I am not able to reach it."

In the Anselm Project Bible: The APB uses "incomprehensible" in both cited verses, applying it to the name in Judges 13:18 and to knowledge in Psalm 139:6. These renderings confirm the clauses' overall presentation rather than identify a precise English equivalent in isolation.
