'Couriers' in the Bible

And king Rehoboam made in their stead shields of bronze, and committed them to the hands of the chief of the couriers who kept the entrance of the king's house.

And it was so, that as often as the king entered into the house of Jehovah, the couriers came and fetched them, and brought them again into the chamber of the couriers.

So the couriers went throughout Israel and Judah with letters from the hand of the king and his officials, and according to the king’s command, saying, “Israelites, return to Yahweh, the God of Abraham, Isaac, and Israel so that He may return to those of you who remain, who have escaped from the grasp of the kings of Assyria.

The couriers traveled from city to city in the land of Ephraim and Manasseh as far as Zebulun, but the inhabitants laughed at them and mocked them.
