New Defender's Study Bible Notes
3:1 I am the man. The prophet, still placing himself in substitution for His sinning nation, here begins the central lamentation of the five. This is different than the two before and the one following, in that it has sixty-six verses instead of twenty-two. That is, the acrostic structure is in triplets of verses; the first three verses each begin with the letter aleph, the second three with the letter beth, and so on through the twenty-two letters. Each verse is quite brief, however, in contrast to the longer verses of the other four lamentations.
