Poetic (Planned?) Parallelism

Idea from Learner's reading currently blowing his mind this week:

"...Jesus must have spent time in organizing his teaching and preparing its form, for unless we assume that this poetic parallelism simply popped into his mind on the spur of the moment, we must conclude that Jesus carefully prepared 'for his classes.' Perhaps some of the time that he sought to be alone was not only for the purpose of prayer but also to prepare what and how he would teach."
