6 and in front of the throne was something like a sea of glass, like crystal. In the middle of the throne and around the throne were four living creatures full of eyes in front and in back.

Darby

6 and before the throne, as a glass sea, like crystal. And in the midst of the throne, and around^D9487 the throne, four living creatures, full of eyes, before and behind;

Darby Bible Notes

around - I use 'round' for what is connected with anything (not necessarily united to it) as a centre, as the tire of a wheel, but 'around' is used for detached objects encircling.

KJV

6 And before the throne [there was] a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, [were] four beasts full of eyes before and behind.
