tachos denotes prompt action or an event expected to occur without delay.

The attested uses divide between urgency in an action—rising, leaving, traveling, or coming—and the prompt occurrence of justice or events that must take place. In every supplied instance, the form is dative singular neuter, while the surrounding clauses specify either an immediate action or a near outcome.

1. Urgency in acting or traveling · dominant

   The dative singular neuter form occurs with actions to be done without delay: in Acts 12:7 the APB renders the command to Peter, "Get up quickly," and in Acts 22:18 it renders the instruction, "Make haste and leave Jerusalem quickly." Acts 25:4 describes Festus going "in haste," while 1 Timothy 3:14 frames the writer's hoped-for coming as soon.

2. Prompt fulfillment or occurrence · common

   The same dative singular neuter form marks an outcome presented as not delayed: in Luke 18:8 the APB renders justice being brought about "speedily," and in Romans 16:20 it renders the crushing of Satan as happening "soon." Revelation 1:1 and Revelation 22:6 place the form in the clause about things that "must soon take place."

   Luke 18:8Romans 16:20Revelation 1:1Revelation 22:6

In the Anselm Project Bible: The APB varies its presentation among "soon," "quickly," "haste," and "speedily," depending on whether the verse concerns an action or an expected outcome. These renderings show the clauses' overall presentation rather than separate English equivalents for each occurrence.
