'Messenger' in the Bible

when one told me, saying, Behold, Saul is dead! and he was in his own sight a messenger of good, I took hold of him, and slew him in Ziklag to whom forsooth I should give a reward for his good tidings:

and charged the messenger, saying, When thou hast ended telling the matters of the war to the king,

And the messenger went; and he came and told David all that Joab had sent him for.

And the messenger said to David, The men prevailed against us, and came out against us into the field, and we were upon them as far as the entrance of the gate.

Then David said to the messenger, Thus shalt thou say to Joab: Let not this thing displease thee, for the sword devours one as well as another: make thy battle strong against the city, and overthrow it; and encourage him.
