That which belonged to the sanctuary, and to the priests, which was taken and separated for that use; which here, and in the following verses, is particularly and separately considered: shall be of five and twenty thousand in length ;
that is, five and twenty thousand reeds from east to west: and of ten thousand in breadth ;
from north to south; see (Ezekiel 45:3) .
