Recall that you were on this side of the valley, while they were on the other side. Then their caravan had to move to lower ground. Had you planned it this way, you could not have done it. But GOD was to carry out a predetermined matter, whereby those destined to be annihilated were annihilated for an obvious reason, and those destined to be saved were saved for an obvious reason. GOD is Hearer, Omniscient.
