What does Exodus 28:27 mean?

And thou shalt make two rings of gold, and shalt put them on the two shoulder-pieces of the ephod underneath, in the forepart thereof, close by the coupling thereof, above the skilfully woven band of the ephod.

And two other rings of gold thou shalt make, and shalt put them on the two sides of the ephod underneath, toward the forepart thereof, over against the other coupling thereof, above the curious girdle of the ephod.

And thou shalt make two rings of gold, and shalt put them on the two shoulder-pieces of the ephod underneath, in the forepart thereof, close by the coupling thereof, above the skilfully woven band of the ephod.

And make two more gold rings and put them on the front of the ephod at the top of the arms, at the join, over the worked band:

and thou hast made two rings of gold, and hast put them on the two shoulders of the ephod, beneath, over-against its front, over-against its joining, above the girdle of the ephod,

Moreover also other two rings of gold, which are to be set on each side of the ephod beneath, that looketh towards the nether joining, that the rational may be fitted with the ephod,

And two rings of gold shalt thou make, and shalt put them upon the two shoulder-pieces of the ephod underneath, to the front thereof just by the coupling thereof, above the girdle of the ephod.
