(1) yadha`, "to see with the eyes or the mind," hence, "know," "understand." Job was urged by Elihu to accept as inscrutable the ways of God, inasmuch as His operations in the physical world are so mighty and mysterious that "we cannot comprehend" them (Job 37:5). Modern science, in unveiling the secrets of Nature, is opening the way for a better understanding of God's creative purpose and plan.
