These are parts, or, the extremities, but small parcels, the outside and visible work. How glorious then are his visible and more inward perfections and operations! Of his ways, i.e. of his works. Of him, i.e. of his power, and wisdom, and providence, and actions. The greatest part of what we see or know of him, is the least part of what we do not know, and of what is in him, or is done by him. The thunder of his power; either,
1. Of his mighty and terrible thunder, which is oft mentioned as an eminent work of God; as Job 28:26, Job 40:9 Psalms 29:3, Psalms 77:18. Or,
2. Of his mighty power, which is aptly compared to thunder, in regard of its irresistible force, and the terror which it causeth to wicked men; this metaphor being used by others in like cases; as among the Grecians, who used to say of their vehement and powerful orators, that they did thunder and lighten; and in Mark 3:17, where powerful preachers are called sons of thunder.
