Charles Ellicott Commentary Jeremiah 43:10

"and say unto them, Thus saith Jehovah of hosts, the God of Israel: Behold, I will send and take Nebuchadrezzar the king of Babylon, my servant, and will set his throne upon these stones that I have hid; and he shall spread his royal pavilion over them." — Jeremiah 43:10 (ASV)

He shall spread his royal pavilion over them.—Here, again, the meaning of the Hebrew word is doubtful. The English Version, as before, follows Luther in interpreting it as the awning or canopy that was stretched over the throne when the king sat in state as judge. Others (e.g., Hitzig) interpret it as the leather covering that was placed over the pavement on which the throne was set, upon which the criminal knelt as on a scaffold to receive the executioner's death-stroke.

Interpreted this way, the prediction assumes a more definite and terrible aspect. The king was to sit upon the stones that Jeremiah had hidden, not merely in his regal pomp, but in the character of an avenger executing the wrath of Jehovah against the rebellious.
