Lamentations 4:21

“Rejoice and be glad, O daughter of Edom, etc.] The land of Idumea, and the inhabitants of it, who did indeed rejoice at the destruction of Jerusalem, (Obidiah 1:12); and here, in an ironic manner, are bid to go on with their mirth, if they could, like the young man in (<211109>Ecclesiastes 11:9), as Aben Ezra observes; for it would not last long, their note would soon be changed: that dwellest in the land of Uz; not the country of Job, which had its name from Uz the son of Nahor, (<180101>Job 1:1 <012221>Genesis 22:21); but a country in Idumea, from whence the whole was so called, and that from Uz the son of Dishan, one of the sons of Seir: or else the sense is, that Edom or Idumea, and the…”

“Rejoice--at our calamities (Psa 137:7). This is a prophecy that Edom should exult over the fall of Jerusalem. At the same time it is implied, Edom's joy shall be short-lived. Ironically she is told, Rejoice while thou mayest (Ecc 11:9). cup--for this image of the confounding effects of God's wrath, see Jer 13:12; Jer 25:15-16, Jer 25:21; as to Edom, Jer. 49:7-22.”

“The prophet ends his elegy with the language of Messianic hope. The earthly king had fallen Lamentations 4:20; but Israel cannot really perish. First then Edom, the representative of the Church’s foes, is ironically told to rejoice. Rejoice she did at the capture of Jerusalem Jeremiah 49:7-22; but her punishment is quickly to follow. Lamentations 4:22 The punishment of thine iniquity is accomplished - literally, Thy iniquity is ended. This is the result of Judah having borne her punishment. And as it is not just to punish twice for the same thing, therefore Jeremiah adds, “He will not send thee again into captivity;” not meaning that under all circumstances Judah would have immunity from…”

“Rejoice - The prophet speaks ironically, Rejoice; but thy joy shall be but for a little time. Drunken - Thou shalt be intoxicated with it, and make thyself naked as drunken men sometimes do. Lamentations 4:22”

“4:21-22 The people of Edom were feeling secure and gloating over Jerusalem’s misfortune, but they, too, would experience punishment for their sins (see Obad 1; Jer 49:7-22). 4:21 Uz was an area east of the Jordan River that extended south to Edom. It was Job’s home (Job 1:1).”

“be glad: Psa 83:3-12, Psa 137:7; Ecc 11:9; Eze 25:6, Eze 25:8, Eze 26:2, Eze 35:11-15; Oba 1:10-16 the land: Gen 36:28; Job 1:1 the cup: Isa. 34:1-17, Isa 63:1-6; Jer 25:15-29, Jer 49:12; Eze 25:12-14, Eze 35:3-9; Amo 1:11; Oba 1:1, Oba 1:10-14; Mal 1:2-4 and shalt: Ch2 28:19; Mic 1:11; Rev 16:15 Lamentations 4:22”

“However, it is not yet all over with Israel. Let the enemy triumph; the guilt of the daughter of Zion will come to an end, and then the guilt of the daughter of Edom will be punished. With this "Messianic hope," as Ewald rightly characterizes the contents of these verses, the lamentation resolves itself into joyous faith and hope regarding the future of Israel. There is no external sign to mark the transition from the depths of lamentation over the hopeless condition of Judah, to new and hopeful confidence, just as in the Psalms there is frequently a sudden change from the deepest lamentation to joyful confidence of final victory. But these transitions have their origin in the firm…”
