1. Growing stronger or more intense · dominant

   In 2 Samuel 3:1, the masculine singular absolute form occurs in the contrast between David's house and Saul's house; the APB renders David as growing “stronger and stronger.” In Exodus 19:19, the same form describes the trumpet sound as it increases; the APB renders it “louder and louder.”

In the Anselm Project Bible: The APB presents the term through “stronger and stronger” for David in 2 Samuel 3:1 and “louder and louder” for the trumpet sound in Exodus 19:19. These expressions show the clauses' presentation rather than fixed English equivalents.
