Ezekiel 1:22

1:22 Over the heads of the living beings was something like a platform, ¹  glittering awesomely like ice, ²  stretched out over their heads.

Revelation 4:6

4:6 and in front of the throne was something like a sea of glass, like crystal. ³ 

In ⁴  the middle of the throne ⁵  and around the throne were four living creatures ⁶  full of eyes in front and in back.

Revelation 21:11

21:11 The city possesses ⁷  the glory of God; its brilliance is like a precious jewel, like a stone of crystal-clear jasper. ⁸ 

Revelation 22:1

22:1 Then ⁹  the angel ¹⁰  showed me the river of the water of life – water as clear as crystal – pouring out ¹¹  from the throne of God and of the Lamb,

¹ tn Or “like a dome” (NCV, NRSV, TEV).

² tn Or “like crystal” (NRSV, NLT).

³ tn This could refer to rock crystal, but it is possible this refers to ice (an older meaning). See BDAG 571 s.v. κρύσταλλος.

⁴ tn Here καί (kai) has not been translated because of differences between Greek and English style.

⁵ tn Perhaps, “in the middle of the throne area” (see L&N 83.10).

⁶ 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.”

⁷ tn Grk “from God, having the glory of God.” Here a new sentence was started in the translation by supplying the words “the city” to refer back to the previous clause and translating the participle (“having”) as a finite verb.

⁸ tn On the term ἰάσπιδι (iaspidi) BDAG 465 s.v. ἴασπις states, “jasper, a precious stone found in various colors, mostly reddish, somet. green…brown, blue, yellow, and white. In antiquity the name was not limited to the variety of quartz now called jasper, but could designate any opaque precious stone. Rv 21:18f. W. λίθος 4:3 (TestSol C 11:8). λίθος ἴασπις κρυσταλλίζων a stone of crystal-clear jasper 21:11 (cp. Is 54:12); perh. the opal is meant here; acc. to some, the diamond.”

⁹ tn Here καί (kai) has been translated as “then” to indicate the implied sequence within the narrative.

¹⁰ tn Grk “he”; the referent (the angel mentioned in 21:9, 15) has been specified in the translation for clarity.

¹¹ tn Grk “proceeding.” Water is more naturally thought to pour out or flow out in English idiom.
