Jeremiah 51:31

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 the LORD God of Abraham, Isaac, and Israel, and he will return to the remnant of you, that are escaped out of the hand of the kings of Assyria.

The king of Babylon hath heard the report of them, and his hands waxed feeble: anguish took hold of him, and pangs as of a woman in travail.

So the posts that rode upon mules and camels went out, being hastened and pressed on by the king’s commandment. And the decree was given at Shushan the palace.

And he wrote in the king Ahasuerus’ name, and sealed it with the king’s ring, and sent letters by posts on horseback, and riders on mules, camels, and young dromedaries:

Now my days are swifter than a post: they flee away, they see no good.

Destruction upon destruction is cried; for the whole land is spoiled: suddenly are my tents spoiled, and my curtains in a moment.

In that night was Belshazzar the king of the Chaldeans slain.

I have laid a snare for thee, and thou art also taken, O Babylon, and thou wast not aware: thou art found, and also caught, because thou hast striven against the LORD.
