Homothumadon describes people acting, speaking, or responding together with a shared purpose.

The adverb marks concerted action or expression by a group: people pray and speak together, make a joint decision, attend to a message collectively, or move against someone as a body. The same pattern occurs in constructive settings and in hostile public action.

1. Concerted group action or expression · dominant

   As an adverb, the form describes a group acting or expressing itself together. In Acts 1:14 the APB renders the group continuing in prayer “with one accord”; in Acts 4:24 they lift their voice to God together, and in Acts 15:25 a decision to choose and send men follows their coming to agreement. The same collective manner can characterize hostile action in Acts 18:12 and Acts 7:57, while Romans 15:6 joins one mind and one mouth in glorifying God.

In the Anselm Project Bible: The APB variously presents the group manner with “with one accord,” “united,” “together,” and “with one mind and one mouth.” These are renderings of the surrounding clauses rather than precise lexical equivalents in every verse.
