13. Who instructed the Spirit of Jehovah? What the Prophet had formerly taught concerning the Lord’s goodness and power he now adds concerning his wisdom. And we ought to observe the connection; for, us carnal sense wickedly limits the power of God to human means, so it improperly subjects his inscrutable counsel to human reasonings. Till God be exalted above all creatures, many difficulties present themselves to interrupt the course of his works; and, therefore, if we form a judgment according to our own opinion, various scruples will immediately arise. Thus, whenever we do not see how God will do this or that, we doubt if it will take place; because what surpasses our reason appears to be impossible. Consequently, as we ought to contrast, the power of God with our weakness, so our insolence ought to be repressed by his incomparable, wisdom.
By inquiring, who guided or directed the Spirit of God, he means that God had no need of a teacher, to go before and inform him about things unknown. Spirit here denotes reason, judgment, or understanding; for he borrows a comparison from the nature of men, that he may more fully accommodate himself to them; and I do not think that this ought to be understood as denoting the essential Spirit of God.
