The following is my translation of the notes and useful applications of the Old Testament Reading for the Wednesday of Populus/Filia Zion (the Second Week of Advent), Malachi 4:1–6, as they are found in Das Weimarische Bibelwerk (1877). Square brackets indicate my own notes and additions. For the useful applications, I recommend the reader see this very helpful article by Dr. Benjamin T. G. Mayes.

I. A sharp admonition and threat against the despisers, and a promise for the pious. (v. 1–3) II. An admonition from the Law. (v. 4) III. A prophecy concerning John the Baptist and his office. (v. 5–6)
Annotated Text
1. “For behold, a day is coming, burning like an oven (in which the Lord’s wrath will burn against the unrepentant, stiff-necked Jews and will consume them together with their temple, cities, and land as fire burns something up in an oven), then all despisers (of Christ and His Word) and (the) godless shall be as stubble, and the coming day will set them on fire,” says the Lord of Sabaoth, “and it will leave neither root nor branch (God will leave to the Jewish people neither a kingdom nor a priesthood, but rather will completely uproot them so that they shall never more come up, just as a tree who has no root cannot ever sprout forth again. However, because the unbelieving Jews still must await the hardest judgment and worst punishment on the Last Day, this prophetic text can at the same also be applied to the final Day of Judgment, in which all the godless together with them shall be destroyed and tossed into the hellish fire).1
(Psalm 1:4; Isaiah 1:31, 5:24)
1 † See Isaiah 66:24, where the prophecy is to be taken exactly in its scope [literal sense?].
2. But for you, who fear My name, * the Sun of Righteousness (Christ Jesus, the Light of the world, John 8:12, and the bright Morningstar, Revelation 22:16, shall rise in your hearts, 2 Peter 1:19, enlighten them with the saving knowledge of God, make them alive and gladden them through His merit and costly-purchased righteousness, warm them through His Spirit, and make them fruitful for all good works) shall arise with salvation in His wings (that is, His rays.1 Just as the sun gives light, warmth, and light to the creatures on earth through its rays, thus Christ will impart spiritual life and eternal salvation to believers through the Word of the Gospel and through the Holy Sacraments), and you shall go out and come in (and find pasture, John 10:9. Christ will also be your Shepherd, who will lead you to the wholesome, fruitful pasture of His Word, under whose protection you will be secure, and your soul will be able to graze) and † increase like the stall-fed calves (you will grow daily in the saving knowledge of God and Christ, His Son, and leap and spring in faith for joy like the stall-fed calves that have feed to the full).
* Luke 1:78
† Isaiah 55:2 (Psalm 84:12; Isaiah 53:11; Daniel 9:24; Psalm 23:1ff.)
1 † Because several parables are set together among the prophets in the east, so also here could the expression “under the wings” (Matthew 23:37) take place in its proper understanding
3. You will trample the godless, for they shall be ashes under your feet on the day in which I will do this (you will, in the power of the victory which Christ has obtained for you and for your good against sin, death, devil, and hell, also overcome enemies through faith and tread them under your feet as earth and ashes, Psalm 91:13; Luke 10:19; Romans 16:20. Also, no bodily enemy, no tyrant, will overpower you or take your salvation from you, but in Christ and through Christ you will overcome them all),” says the Lord of Sabaoth.
(Isaiah 25:10; Zechariah 10:5)
4. “Remember the * Law of Moses, my (faithful) servant, which I commanded him at Mount Horeb to all Israel, together with the commandments and laws (diligently keep the Ten Commandments, the ecclesial laws, and the civil laws which I have given to you through My servant Moses on Mount Horeb, otherwise called Sinai. Because Malachi was the last prophet of the Old Testament, he therefore wanted with this admonition, so to speak, seal and close it, for the Jews were to be guarded and shut up under the Mosaic Law for the faith that would be revealed, and the Law was to be their disciplinarian to Christ, Galatians 3:23–24). He then should afterward bring forth the doctrine of the Gospel1 from the bosom of His heavenly Father, John 1:18.
* Exodus 20:1ff. (Hebrews 3:5)
1 † Because the commandments and laws (that is, the Levitical and civil law) are particularly mentioned, so there is no doubt that along with the very earnest command and warning (Deuteronomy 18:18ff.), here the types hidden beneath them are also pointed out (cf. John 5:46ff.).
5. Behold, I * will send you the prophet Elijah (John the Baptist, who will rebuke the false doctrine and the godless life unafraid in the Spirit and power of Elijah) before then comes the great and terrible day of the Lord (the day of the first coming of Christ, which was a great and glorious day because Christ obtained great treasures and glorious benefits for believers on that day; however, it was a terrible day for the devil and all his hellish power, because Christ came to execute vengeance against him, Isaiah 61:2, to crush his head, Genesis 3:15, and to destroy his kingdom along with his works, 1 John 3:8).
* Matthew 11:14, 17:12 (Mark 9:12–13)
6. He shall convert the hearts of the fathers to the children, and the hearts of the children to their fathers (in a similar manner as the prophet Elijah with great zeal rebuked and abolished the idolatry of Baal, and led them back to the old true religion to which the old patriarchs were devoted, 1 Kings 18:39, so also will John the Baptist likewise zealously rebuke the false doctrine of the Pharisees and scribes and convert the people again to the true God, whom their forefathers had served according to His Word.1 Therefore, you Jews, listen to John the Baptist and follow his teaching, and with true faith receive the Messiah, whom he will point to with his finger [John 1:29–31]), so that I do not come and strike2 earth with the ban (so that I may not destroy you and hurl you into eternal condemnation on account of your unbelief).
(Luke 1:17; 1 Thessalonians 2:16; Hebrews 10:18–31)
1 † Which includes the parents with the children, and the children with the parents, that is, all of them together (cf. Matthew 3:5). This adheres more closely to the Hebrew עַל which happens often in this understanding (see Genesis 32:12; Exodus 20:5; and Judges 15:8).
2 † This last thing (alas!), the sad outcome has demonstrated. See Deuteronomy 32.
