The cherubs spread forth their wings over the place of the ark, so that the cherubs covered the ark and the staves thereof from above. And the staves were drawn out, and the heads of the staves were seen from the holy place toward the faces of the sanctuary; but they were not seen without (1 Kings 8:7, 8).
