'Envoys' in the Bible

Then he sent envoys to visit King Ahab of Israel and told him, "This is what Ben-hadad says:

After delivering Ahab's answer, the envoys returned with this message: "This is what Ben-hadad says: "I've sent my envoys to you to tell you that your silver, gold, wives, and children are to be given to me.

So he told Ben-hadad's envoys, "Tell his majesty the king, "Everything that you asked for the first time I will do, but this thing I cannot do.'" So the envoys left to deliver Ahab's response. They returned a little while later.
