1sn Beginning with 4:1, the verse numbers through 4:6 in the English Bible differ from the verse numbers in the Hebrew text (BHS), with 4:1 ET = 3:19 HT, 4:2 ET = 3:20 HT, etc., through 4:6 ET = 3:24 HT. Thus the book of Malachi in the Hebrew Bible has only three chapters, with 24 verses in ch. 3.

2sn This day is the well-known “day of the Lord” so pervasive in OT eschatological texts (see Joel 2:30-31; Amos 5:18; Obad 15). For the believer it is a day of grace and salvation; for the sinner, a day of judgment and destruction.

3tn Heb “so that it” (so NASB, NRSV). For stylistic reasons a new sentence was begun here in the translation.

4tn Here the Hebrew word צְדָקָה (ts˙daqah), usually translated “righteousness” (so KJV, NIV, NRSV, NLT; cf. NAB “justice”), has been rendered as “vindication” because it is the vindication of God’s people that is in view in the context. Cf. BDB 842 s.v. צְדָקָה 6; “righteousness as vindicated, justification, salvation, etc.”

sn The expression the sun of vindication will rise is a metaphorical way of describing the day of the Lord as a time of restoration when God vindicates his people (see 2 Sam 23:4; Isa 30:26; 60:1, 3). Their vindication and restoration will be as obvious and undeniable as the bright light of the rising sun.

5sn The point of the metaphor of healing wings is unclear. The sun seems to be compared to a bird. Perhaps the sun’s “wings” are its warm rays. “Healing” may refer to a reversal of the injury done by evildoers (see Mal 3:5).

6tn Heb “you will go out and skip about.”

7sn Horeb is another name for Mount Sinai (cf. Exod 3:1).

8tn Heb “which I commanded him in Horeb concerning all Israel, statutes and ordinances.”

9sn I will send you Elijah the prophet. In light of the ascension of Elijah to heaven without dying (2 Kgs 2:11), Judaism has always awaited his return as an aspect of the messianic age (see, e.g., John 1:19-28). Jesus identified John the Baptist as Elijah, because he came in the “spirit and power” of his prototype Elijah (Matt 11:14; 17:1-13; Mark 9:2-13; Luke 9:28-36).

10tn Heb “he will turn the heart[s] of [the] fathers to [the] sons, and the heart[s] of [the] sons to their fathers.” This may mean that the messenger will encourage reconciliation of conflicts within Jewish families in the postexilic community (see Mal 2:10; this interpretation is followed by most English versions). Another option is to translate, “he will turn the hearts of the fathers together with those of the children [to me], and the hearts of the children together with those of their fathers [to me].” In this case the prophet encourages both the younger and older generations of sinful society to repent and return to the Lord (cf. Mal 3:7). This option is preferred in the present translation; see Beth Glazier-McDonald, Malachi (SBLDS), 256.

11tn Heb “[the] ban” (חֵרֶם, kherem). God’s prophetic messenger seeks to bring about salvation and restoration, thus avoiding the imposition of the covenant curse, that is, the divine ban that the hopelessly unrepentant must expect (see Deut 7:2; 20:17; Judg 1:21; Zech 14:11). If the wicked repent, the purifying judgment threatened in 4:1-3 will be unnecessary.
