tachus describes prompt action or an event expected without delay, and in one instruction marks readiness to listen.

The predominant use marks action to be taken without delay or an arrival presented as near: instructions summon companions, servants are told to bring the robe, reconciliation is urged on the road, and the coming is announced. In James 1:19, it characterizes a person’s readiness in relation to hearing.

1. Without delay in action or arrival · dominant

   The accusative neuter forms occur where timing is pressed: in Acts 17:15 the APB renders the instruction for Silas and Timothy to come “as quickly as possible”; in Luke 15:22 the father directs the servants, “Quick! Bring the best robe.” Matthew 5:25 urges reconciliation “quickly” while on the road, and Revelation 22:12 presents the coming as “soon.”

   In James 1:19, the nominative singular masculine form describes each person in the instruction to be “quick to hear,” set alongside being slow to speak and slow to anger.

   James 1:19

In the Anselm Project Bible: The APB uses “as quickly as possible,” “Quick!,” “quickly,” and “soon” in the verses concerning urgent action or arrival, and “quick to hear” in James 1:19. These are verse-level renderings rather than definitions.
