Adialeiptos describes something maintained without interruption, as in grief and prayerful remembrance.

The two attestations describe an uninterrupted condition or practice: grief and heart-anguish in Romans 9:2, and remembrance in prayers in 2 Timothy 1:3.

1. Uninterrupted condition or practice · dominant

   In Romans 9:2, the nominative singular feminine form occurs in the clause concerning great grief and anguish of heart; the APB renders the verse with anguish that is “unceasing.” In 2 Timothy 1:3, the accusative singular feminine form occurs in the statement about remembering someone in prayers night and day; the APB renders that remembrance as “continually.”

   Romans 9:22 Timothy 1:3

In the Anselm Project Bible: The APB presents the relevant clauses with “unceasing” in Romans 9:2 and “continually” in 2 Timothy 1:3. These render the verse contexts rather than establishing a separate meaning in each verse.
