4:2 The source for the title Sun of Righteousness might have been the winged sun disk that is ubiquitous in ancient Near Eastern iconography. Here it might be a title for the Messiah or a figurative description of a new era of righteousness in which God will overturn the curse of sin. Israel’s spiritual restoration, or healing, would be based on God’s cleansing the people and forgiving their sins (see Jer 33:6-8; cp. Jer 8:14-15). It would result from a collective confession of sin and their turning back to God (Mal 3:7; cp. Jer 14:19-20). • in his wings: Outstretched wings are a symbol of God’s protection and rescue (see Exod 19:4; Deut 32:10-11; Ps 17:8; 18:10).

4:4-6 The book concludes with an epilogue containing appeals to Moses and Elijah, two ideal models of faith in the Lord and of the ideals of the Law and Prophets (see Matt 17:1-4). The two are upheld as examples for Malachi’s audience to follow. In ancient Hebrew tradition, the two appeals may have served as postscripts for the scroll that contained the twelve Minor (shorter) Prophets. If so, the first postscript (Mal 4:4) connects the scroll to the Law of Moses. The second (4:5-6) ties the scroll of the Minor Prophets to the Major (longer) Prophets—Isaiah, Jeremiah, and Ezekiel.
