Under the whole heaven he lets it go, and his lightning to the corners of the earth.
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
He directeth it under the whole heaven,.... His voice of thunder, which rolls from one end of the heaven to the other: he charges the clouds with it, and directs both it and them where they shall go and discharge; what tree, house, or man, it shall strike; and where the rain shall fall when the clouds burst: yet Pliny (x) atheistically calls thunder and lightning chance matters.
directeth it--however zigzag the lightning's course; or, rather, it applies to the pealing roll of the thunder. God's all-embracing power. ends--literally, "wings," "skirts," the habitable earth being often compared to an extended garment (Job 38:13; Isa 11:12).
