And there were eight boards; and their sockets were sixteen sockets of silver, under every board two sockets.
All Commentaries on Exodus 36:30 Go To Exodus 36
Augustine of Hippo
AD 430
Sometimes, however, under one figure of either an act or an utterance, two terms may have one meaning. Thus the boards which were fitted together into the construction of the ark signify both the faithful and the eight souls who were saved in the same ark. Similarly, in the Gospel, in the parable of the sheepfold, Christ himself is both the shepherd and the door.
