Albert Barnes 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)

My servant - See Jeremiah 25:9 note.

That I have hid - that is, that I have embedded in the mortar by the instrumentality of my prophet.

Pavilion - Rather, canopy. It probably means the parasol held over kings, which had a tall and thick pole, grasped with both hands, and in the early times a somewhat small circular top.
