Peter Pett's Commentary on the Bible
Isaiah 31 - Introduction
Chapter 31 The Fifth Woe On Those Who Trust To Egypt And To The Strength Of Their Horse Propelled Armaments. Rather They Must Trust In Yahweh Who Will Fight For Them.
This chapter is a chapter of contrast. On the one hand are those who fatally trust in Egypt because of their horses and chariots, And on the other the call goes out to trust in Yahweh Who will deliver without needing either, for He will hover over Jerusalem as He did at the Exodus and will smite their enemy with His voice.
