'Posts' in the Bible

So the posts went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying, Ye children of Israel, turn again unto Jehovah, the God of Abraham, Isaac, and Israel, that he may return to the remnant that are escaped of you out of the hand of the kings of Assyria.

So the posts passed from city to city through the country of Ephraim and Manasseh, even unto Zebulun: but they laughed them to scorn, and mocked them.
