Charles Ellicott Commentary Revelation 2:22

"Behold, I cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of her works." — Revelation 2:22 (ASV)

I will cast her into a bed.—The chamber of voluptuousness will become the chamber of sickness. The spot of the sin shall be the scene of punishment (Compare to 1 Kings 21:19).
