'Messenger' in the Bible

So the messenger left Joab, set out for Jerusalem, and disclosed to David everything that Joab had sent him to say.

The messenger told David, "The men surprised us and attacked us in the field, but we drove them back to the entrance of the city gate.

David responded to the messenger, "Here's what you're to tell Joab: "Don't be troubled by this incident, because the battle sword consumes one or another from time to time. Consolidate your attack against the city and conquer it.' Be sure to encourage him."

Then a messenger arrived to inform David, "The loyalties of the men of Israel have shifted to Absalom."
