John Gill Commentary 1 Kings 8:7

"For the cherubim spread forth their wings over the place of the ark, and the cherubim covered the ark and the staves thereof above." — 1 Kings 8:7 (ASV)

For the cherubim spread forth [their] two wings over the place
of the ark
The most holy place where the ark stood, even from wall to wall:

and the cherubim covered the ark, and the staves thereof above ;
so that neither could be seen.
