asphales describes what is certain enough to establish the facts or secure enough to provide steadfast protection.

The dominant use concerns a matter that can be established with certainty: official inquiries seek clear facts or something definite in Acts 21:34, Acts 22:30, and Acts 25:26. It also describes secure reliability, applied to hope as an anchor and to repeated instruction as protection in Hebrews 6:19 and Philippians 3:1.

   In Hebrews 6:19, the accusative singular feminine form describes hope alongside the image of an anchor, which the APB renders “secure and firm.” In Philippians 3:1, the nominative singular neuter form occurs in the statement that writing the same things is a safeguard for the readers.

In the Anselm Project Bible: The APB varies its presentation among “facts,” “secure matter,” “definite,” “secure and firm,” and “safeguard.” These expressions confirm the clauses' overall movement between certainty and security rather than providing a fixed English equivalent.
