and in front of the throne was something like a sea of glass, like crystal. ¹  In ²  the middle of the throne ³  and around the throne were four living creatures ⁴  full of eyes in front and in back.

Ex 38:8; 1Ki 7:23; Job 28:17; Eze 1:4,5; Eze 1:5-28; Eze 1:18; Eze 1:22; Eze 10:12; Eze 10:14; Re 4:8,9; Re 4:8; Re 5:6; Re 5:6,14; Re 6:1; Re 7:11; Re 7:17; Re 14:3; Re 15:2; Re 15:7; Re 19:4; Re 21:11; Re 22:1

¹ tn This could refer to rock crystal, but it is possible this refers to ice (an older meaning). See BDAG 571 s.v. κρύσταλλος.

² tn Here καί (kai) has not been translated because of differences between Greek and English style.

³ tn Perhaps, “in the middle of the throne area” (see L&N 83.10).

⁴ tn On the meaning of ζῴον (zwon) BDAG 431 s.v. 2 states, “Of the four peculiar beings at God’s throne, whose description Rv 4:6-9 reminds one of the ζῷα in Ezk 1:5ff, the cherubim. S. also Rv 5:6, 8, 11, 14; 6:1, 3, 5-7; 7:11; 14:3; 15:7; 19:4.”
