“At this my heart also pounds and leaps from its place.
Thunder and lightning, which usually go together, are sensible indications of the glory and majesty, the power and terror, of Almighty God, one to the ear and the other to the eye; in these God leaves not himself without witness of his greatness, as, in the rain from heaven and fruitful seasons, he leaves not himself without witness of his goodness (Act 14:17), even to the most stupid and unthinking.
Commenting on Job 37:1-5
At this also my heart trembleth,.... At the greatness and majesty of God, not only as displayed in those works of his before observed, but as displayed in those he was about to speak of: such terrible majesty is there with God, that all rational creatures tremble at it; the nations of the world, the kings and great men of the earth, and even the devils themselves, Isa 64:2.
At this also my heart trembleth, and is moved out of his place. (a) At the marvelling of the thunder and lightnings: by which he declares that the faithful are lively touched with the majesty of God, when they behold his works.
