Knowest thou? either,
1. Simply, and by speculation, dost thou understand them? Or,
2. Practically, or operatively, so as to establish or rule them, as the next clause implies. The ordinances of heaven; the laws, which are firmly established concerning their order, motion, or rest and their powerful influences upon this lower world. Didst thou give these laws? or dost thou perfectly know them? Canst thou set the dominion thereof in the earth? canst manage and overrule their influences, that they shall bring such seasons and such weather as thou wouldst have?
