Who hath divided a water-course, &c. For the showers of rain, which come down orderly and gradually, as if they were conveyed in pipes or channels; which, without the care of God's providence, would fall confusedly, and overwhelm the earth. Or a way for the lightning For lightning and thunder? Who opened a passage for them out of the cloud in which they were imprisoned? And these are joined with the rain, because they are commonly accompanied with great showers of rain.
