Matthew Henry on Lamentations 4:21–end
David's psalms of lamentation commonly conclude with some word of comfort, which is as life from the dead and light shining out of darkness; so does this lamentation here in this chapter. The people of God are now in great distress, their aspects all doleful, their prospects all frightful, and their ill-natured neighbours the Edomites insult over them and do all they can to exasperate their destroyers against them.

John Gill on Lamentations 4:21
Rejoice and be glad, O daughter of Edom,.... The land of Idumea, and the inhabitants of it, who did indeed rejoice at the destruction of Jerusalem, Obadiah 1:12; and here, in an ironic manner, are bid to go on with their mirth, if they could, like the young man in 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, Job 1:1; 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 inhabitants of it, dwelt upon the borders of…
