Leviticus 10:3

10:3 Moses then said to Aaron, “This is what the Lord spoke: ‘Among the ones close to me I will show myself holy, ¹  and in the presence of all the people I will be honored.’” ²  So Aaron kept silent.

Malachi 3:1

3:1 “I am about to send my messenger, ³  who will clear the way before me. Indeed, the Lord ⁴  you are seeking will suddenly come to his temple, and the messenger ⁵  of the covenant, whom you long for, is certainly coming,” says the Lord who rules over all.

Hebrews 12:28

12:28 So since we are receiving an unshakable kingdom, let us give thanks, and through this let us offer worship pleasing to God in devotion and awe.

¹ tn The Niphal verb of the Hebrew root קָדַשׁ (qadash) can mean either “to be treated as holy” (so here, e.g., BDB 873 s.v. קָּדַשׁ, LXX, NASB, and NEB) or “to show oneself holy” (so here, e.g., HALOT 1073 s.v. קדשׁnif.1, NIV, NRSV, NLT; J. Milgrom, Leviticus [AB], 1:595, 601-3; and J. E. Hartley, Leviticus [WBC], 133-34). The latter rendering seems more likely here since, in the immediate context, the Lord himself had indeed shown himself to be holy by the way he responded to the illegitimate incense offering of Nadab and Abihu. They had not treated the Lord as holy, so the Lord acted on his own behalf to show that he was indeed holy.

² tn In this context the Niphal of the Hebrew root כָּבֵד (kaved) can mean “to be honored” (e.g., NASB and NIV here), “be glorified” (ASV, NRSV and NLT here), or “glorify oneself, show one’s glory” (cf. NAB; e.g., specifically in this verse HALOT 455 s.v. כבדnif.3; J. Milgrom, Leviticus [AB], 1:595, 603-4; and J. E. Hartley, Leviticus [WBC], 126, 134). Comparing this clause with the previous one (see the note above), the point may be that when the Lord shows himself to be holy as he has done in 10:1-2, this results in him being honored (i.e., reverenced, feared, treated with respect) among the people. This suggests the passive rendering. It is possible, however, that one should use the reflexive rendering here as in the previous clause. If so, the passage means that the Lord showed both his holiness and his glory in one outbreak against Nadab and Abihu.

³ tn In Hebrew the phrase “my messenger” is מַלְאָכִי (mal’akhi), the same form as the prophet’s name (see note on the name “Malachi” in 1:1). However, here the messenger appears to be an eschatological figure who is about to appear, as the following context suggests. According to 4:5, this messenger is “Elijah the prophet,” whom the NT identifies as John the Baptist (Matt 11:10; Mark 1:2) because he came in the “spirit and power” of Elijah (Matt 11:14; 17:11-12; Lk 1:17).

⁴ tn Here the Hebrew term הָאָדוֹן (ha’adon) is used, not יְהוָה (yÿhvah, typically rendered Lord). Thus the focus is not on the Lord as the covenant God, but on his role as master.

⁵ sn This messenger of the covenant may be equated with my messenger (that is, Elijah) mentioned earlier in the verse, or with the Lord himself. In either case the messenger functions as an enforcer of the covenant. Note the following verses, which depict purifying judgment on a people that has violated the Lord’s covenant.
