Isaiah
Isaiah 40:13BSB·traditional attribution

Who has directed the Spirit of the LORD, or informed Him as His counselor?

John Calvin Reformed @genevareformer

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.

Matthew Henry Presbyterian @wholebiblehenry

The scope of these verses is to show what a great and glorious being the Lord Jehovah is, who is Israel's God and Saviour. It comes in here, 1. To encourage his people that were captives in Babylon to hope in him, and to depend upon him for deliverance, though they were ever so weak and their oppressors ever so strong. 2.

John Gill Reformed Baptist @doctorgill

Who hath directed the Spirit of the Lord,.... In the creation of all things, in garnishing the heavens, and moving upon the face of the waters? not anyone, angel or man; there were none with him, nor did he need any to guide and direct him what to do (s): or being his counsellor, hath taught him?
