Katischuo denotes gaining the upper hand, whether voices prevail, hostile gates do not prevail, or people are enabled to escape.

The attested uses concern prevailing or gaining the upper hand: urgent voices prevail in Luke 23:23, the gates of Hades are said not to prevail against the church in Matthew 16:18, and those praying in Luke 21:36 seek strength to escape impending events.

1. Prevailing against or over a person or group · dominant

   In Luke 23:23, the imperfect active plural form occurs as urgent voices press for crucifixion; the APB renders the outcome, “their voices prevailed.” In Matthew 16:18, the future active plural form is negated in the statement that the gates of Hades “will not prevail against it.”

   In Luke 21:36, the aorist active subjunctive plural form occurs in a prayer that the hearers may have strength “to escape all these things that are about to take place”; the APB presents escape and standing before the Son of Man as the requested outcome.
