Charles Ellicott Commentary 1 Kings 6:4

"And for the house he made windows of fixed lattice-work." — 1 Kings 6:4 (ASV)

Windows of narrow lights. —The marginal reading, “windows broad within and narrow without”—splayed as in ordinary Gothic architecture—is supported by very good authorities; but the most probable meaning is “windows with fixed beams”—that is, with fixed lattices, like jalousies, useful for ventilation, but immovable, so that no one could look out or in.
