This plural noun appears only in Job 37:16 in a textually uncertain passage, apparently referring to God's wondrous works in nature, particularly cloud formations. The word derives from a root meaning 'to be extraordinary or difficult.' Elihu is calling Job's attention to the marvels of God's providential control over weather—the 'wonders' of the one perfect in knowledge. Some scholars emend the text, but the sense of divine marvels fits the context well.
