1 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.
2 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.”
3 tn Grk “and its wall”; the referent of the pronoun (the city) has been specified in the translation for clarity. Here καί (kai) has not been translated because of differences between Greek and English style.
4 tn The phrase ἡ ἐνδώμησις τοῦ τείχους (Jh endwmhsi" tou teicou") is difficult to translate precisely. BDAG 334 s.v. ἐνδώμησις states, “primary mng. ‘interior structure’; in our lit. prob.=construction, hence material τοῦ τείχους Rv 21:18.” The phrase could then be translated, “the foundation of the city wall was jasper” or “the material used for the wall of the city was jasper.” The latter alternative has been used in the translation because the text goes on to discuss the foundation in 21:19 (using the term θεμέλιος [qemelios]), which is somewhat redundant if the foundation is mentioned here.
5 tn Or “transparent crystal.” See L&N 6.222, which notes the emphasis is on transparency here. The same Greek word, καθαρός (kaqaros), means both “pure” (referring to the gold) and “transparent” (referring to the glass).
