'Messenger' in the Bible

He commanded the messenger, “When you’ve finished telling the king all the details of the battle—

Then the messenger left.When he arrived, he reported to David all that Joab had sent him to tell.

The messenger reported to David, “The men gained the advantage over us and came out against us in the field, but we counterattacked right up to the entrance of the gate.

David told the messenger, “Say this to Joab: ‘Don’t let this matter upset you because the sword devours all alike. Intensify your fight against the city and demolish it.’ Encourage him.”
