Ps 105:28 He sent [thick, oppressive] darkness and made the land dark; And Moses and Aaron did not rebel against His words. [Ex 10:22; Ps 99:7]
Rev 4:6 and in front of the throne there was something like a sea or large expanse of glass, like [the clearest] crystal. In the center and around the throne were four living creatures who were full of eyes in front and behind [seeing everything and knowing everything that is around them]. [Ps 99:1; Is 6:2, 3; Ezek 1:5, 18]
