John Gill Commentary 1 Kings 7:4

"And there were beams in three rows, and window was over against window in three ranks." — 1 Kings 7:4 (ASV)

And there were windows in three rows
Both in the second and third stories, east, north, and south, there being none in the west, where the porch stood:

and light was against light in three ranks ;
or the windows, through which light was let, answered to each other.
