'Couriers' in the Bible

So the couriers went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying, "You children of Israel, turn again to Yahweh, the God of Abraham, Isaac, and Israel, that he may return to the remnant that have escaped of you out of the hand of the kings of Assyria.

So the couriers passed from city to city through the country of Ephraim and Manasseh, even to Zebulun: but they ridiculed them, and mocked them.
