Judges 5

Judges 5 is a poem. This is the one key fact that must be noted if this chapter is to be properly understood. Some elements of poetry are important:

Imagination - the event which the poet reflects upon happened, but in his presentation he uses his imagination to shape his words.
Focus - poetry focuses on aspects of a story, some details are magnified, some are omitted.
Poetry is not science of any kind, i.e. it is not the social science of history.
Purpose - while there are forms of poetry the purpose of which is to record and maintain historical accounts, e.g. a saga, other forms of poetry have the purpose of celebration or lamentation, the reader or hearer of the poem is intended to respond emotionally to the text.

In Hebrew poetry rhyme is too easy and is not an element, features such as repetition (parallelism), rhythm, metre feature prominently and give a heightened style to a poem in contrast to a prose account.
