It is certainly likely that there would have been people in the army that thought Israel should have kept the horses and chariots for future wars, and God’s leaders must learn to be strong and resist giving in to people who advise against following the commands of God. God’s commands do not always seem the best from a fleshly point of view, but they always are the best.
