Charles Ellicott Commentary Jeremiah 22:14

"that saith, I will build me a wide house and spacious chambers, and cutteth him out windows; and it is ceiled with cedar, and painted with vermilion." — Jeremiah 22:14 (ASV)

Large chambers. —As before, “upper storeys or chambers.”

Cutteth him out windows. —The verb is the same as that used in Jeremiah 4:30 for dilating the eyes by the use of antimony, and implies accordingly the construction of windows of unusual width. These, after the Eastern fashion, were fitted with lattice-work, or shielded by curtains.

Vermilion. —Probably the red pigment (mercury sulfide?) still conspicuous in the buildings of Egypt. The word meets us again in Ezekiel 23:14. The king was probably impelled by a vainglorious desire to imitate the magnificence of the Egyptian king (Pharaoh-nechoh) who had placed him on the throne.
