A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown [1882] at sacred-texts.com
The title more frequently given by the Jews to these Elegies is, "How" (Hebrew, Eechah), from the first word, as the Pentateuch is similarly called by the first Hebrew word of Gen 1:1. The Septuagint calls it "Lamentations," from which we derive the name. It refers not merely to the events which occurred at the capture of the city, but to the sufferings of the citizens (the penalty of national sin) from the very beginning of the siege; and perhaps from before it, under Manasseh and Josiah (Ch2 33:11; Ch2 35:20-25); under Jehoahaz, Jehoiakim, and Zedekiah (Ch2 36:3-4, Ch2 36:6-7, Ch2 36:10-11, &c.). LOWTH says, "Every letter is written with a tear, every word the sound of a broken heart." The style is midway between the simple elevation of prophetic writing and the loftier rhythm of Moses, David, and Habakkuk. Terse conciseness marks the Hebrew original, notwithstanding Jeremiah's diffuseness in his other writings. The Elegies are grouped in stanzas as they arose in his mind, without any artificial system of arrangement as to the thoughts. The five Elegies are acrostic: each is divided into twenty-two stanzas or verses. In the first three Elegies the stanzas consist of triplets of lines (excepting Lam 1:7; Lam 2:19, which contain each four lines) each beginning with the letters of the Hebrew alphabet in regular order (twenty-two in number). In three instances (Lam 2:16-17; Lam 3:46-51; Lam 4:16-17) two letters are transposed. In the third Elegy, each line of the three forming every stanza begins with the same letter. The stanzas in the fourth and fifth Elegies consist of two lines each. The fifth Elegy, though having twenty-two stanzas (the number of letters in the Hebrew alphabet), just as the first four, yet is not alphabetical; and its lines are shorter than those of the others, which are longer than are found in other Hebrew poems, and contain twelve syllables, marked by a cÃ&brvbr;sura about the middle, dividing them into two somewhat unequal parts. The alphabetical arrangement was adopted originally to assist the memory. GROTIUS thinks the reason for the inversion of two of the Hebrew letters in Lam 2:16-17; Lam 3:46-51; Lam 4:16-17, is that the Chaldeans, like the Arabians, used a different order from the Hebrews; in the first Elegy, Jeremiah speaks as a Hebrew, in the following ones, as one subject to the Chaldeans. This is doubtful.
