Last week I did several posts on figures of speech in the Bible. Here are a few online sources that address the topic.
Figures of Speech in the Bible
Figures of Speech by Robert I. Bradshaw
Interpreting the Bible: a handbook of terms and methods
Alliterated Sermon Outlines by John G. Butler
In light of past discussions, I found Butler statement interesting: "It may surprise some that the Bible does have some good illustrations of alliteration and other literary devices which give a preacher a good precedence for alliterating his sermons."
It should not pass our attention, though, that this alliteration was used in poetic writing. As far as I can tell, there are no biblical alliterative sermons.
