Seirim are demons

Isaiah 13:21:

Mongooses will lay there, and their houses will be filled with ochim; benoth yaanah will dwell there, and seirim will dance there.

Rashi:

"seirim" -- demons.

Israel compared to stars

Isaiah 13:14:

And you (Babylonia/Nebuchadnezzar) said, "I will ascend, over the stars of G-d I will raise my throne..."

Rashi:

"the stars of G-d" -- Israel.
