³ tn Or “transparent crystal.” See L&N 6.222, which notes the emphasis is on transparency here. The same Greek word, καθαρός (katharos), means both “pure” (referring to the gold) and “transparent” (referring to the glass).

¹ tn The word is from זָכַךְ (zakhakh, “clear”). It describes a transparent substance, and so “glass” is an appropriate translation. In the ancient world it was precious and so expensive.

² sn S. R. Driver suggests that they saw the divine Glory, not directly, but as they looked up from below, through what appeared to be a transparent blue sapphire pavement (Exodus, 254).

⁴ tn Heb “and like the body of heaven for clearness.” The Hebrew term שָׁמַיִם (shamayim) may be translated “heaven” or “sky” depending on the context; here, where sapphire is mentioned (a blue stone) “sky” seems more appropriate, since the transparent blueness of the sapphire would appear like the blueness of the cloudless sky.

¹ tn The meaning of the participle ἀληθεύοντες (alētheuontes; from the verb ἀληθεύω [alētheuō]) is debated. In classical times the verb could mean “to speak the truth,” or “to be true, to prove true.” In the LXX it appears five times (Gen 20:16; 42:16; Prov 21:3; Isa 44:26; Sir 34:4) and translates four different Hebrew words; there it is an ethical term used of proving or being true, not with the idea of speaking the truth. In the NT the only other place the verb appears is in Gal 4:16 where it means “to speak the truth.” However, in Ephesians the concept of “being truthful” is the best sense of the word. In contrast to the preceding verse, where there are three prepositional phrases to denote falsehood and deceit, the present word speaks of being real or truthful in both conduct and speech. Their deceit was not only in their words but also in their conduct. In other words, the believers’ conduct should be transparent, revealing the real state of affairs, as opposed to hiding or suppressing the truth through cunning and deceit. See H. W. Hoehner, Ephesians, 564-65, and R. Bultmann, TDNT 1:251.

² tn This line reads literally, “and with the rich in his death.” בְּמֹתָיו (b^emotayv) combines a preposition, a plural form of the noun מוֹת (mot), and a third masculine singular suffix. The plural of the noun is problematic and the יו may be the result of virtual dittography. The form should probably be emended to בָּמָתוֹ (bamato, singular noun). The relationship between this line and the preceding one is uncertain. The parallelism appears to be synonymous (note “his grave” and “in his death”), but “criminals” and “the rich” hardly make a compatible pair in this context, for they would not be buried in the same kind of tomb. Some emend עָשִׁיר (ʿashir, “rich”) to עָשֵׂי רָע (ʿase raʿ, “doers of evil”) but the absence of the ayin (ע) is not readily explained in this graphic environment. Others suggest an emendation to שְׂעִירִים (s^eʿirim, “he-goats, demons”), but the meaning in this case is not entirely transparent and the proposal assumes that the form suffered from both transposition and the inexplicable loss of a final mem. Still others relate עָשִׁיר (ʿashir) to an alleged Arabic cognate meaning “mob.” See HALOT 896 s.v. עָשִׁיר. Perhaps the parallelism is antithetical, rather than synonymous. In this case, the point is made that the servant’s burial in a rich man’s tomb, in contrast to a criminal’s burial, was appropriate, for he had done nothing wrong.

³ tn Further difficulties are created by the meaning of καρδία (kardia) in 3:19. Although it may be agreed that the term generally refers to the “center and source of the whole inner life, w. its thinking, feeling, and volition” (BDAG 508 s.v. l.b), this may be further subdivided into references to (a) “the faculty of thought…as the organ of natural and spiritual enlightenment,” that is, the mind; (b) “the will and its decisions”; (c) “the emotions, wishes, desires,” i.e., the emotions or feelings; or (d) “moral decisions, the moral life,” that is, the part of the individual where moral decisions are made, which is commonly called the conscience. Thus καρδία in 3:19 could refer to either the mind, the will, the emotions, or the conscience, and it is not transparently clear which concept the author has primarily in view. In light of the overall context, which seems to discuss the believer’s assurance of his or her standing before God (ἔμπροσθεν αὐτοῦ [emprosthen autou] in 3:19 and the mention of παρρησία [parrēsia, “boldness” or “confidence”] in 3:21) it seems probable that the conscience, that aspect of one’s καρδία which involves moral choices and the guilt or approval for having made them, is primarily in view here. Thus the meaning “convince” is preferred for the verb πείθω (peithō), since the overall subject seems to be the believer’s assurance of his or her standing before God, especially in the case when (v. 20) the believer’s conscience attempts to condemn him on account of sin.
