1 Kings 6:4

And for the house he made windows of narrow lights. Or "open, shut" , which could be both, having shutters to them, to open or shut at pleasure; windows which they could open, and look through at them, or shut when they pleased; the Targum is,"open within, and shut without;''or, as others understand it, they were wide within, and narrow without; by being narrow without, the house was preserved from bad weather, as well as could not so easily be looked into by those without; and by being broader within, the light that was let in spread itself within the house; which some interpret only of the holy place, the most holy place having, as they suppose, no windows in it, which yet is not certain: now these windows may denote the word and ordinances of the church of God, whereby light is communicated to men; which in the present state is but narrow or small, in comparison of the new Jerusalem church state, and the ultimate glory; and especially so it was under the legal dispensation, which was very obscure; see So 2:9 Isa 55:8.
