9 For the eyes of the Lord range throughout the earth to strengthen those whose hearts are fully committed to him. You have done a foolish thing, and from now on you will be at war."
3 The eyes of the Lord are everywhere, keeping watch on the wicked and the good.
(Read Proverbs 15:3)
Secret sins, services, and sorrows, are under God's eye. This speaks comfort to saints, and terror to sinners.
10 "Who dares despise the day of small things, since the seven eyes of the Lord that range throughout the earth will rejoice when they see the chosen capstone in the hand of Zerubbabel?"
(Read Zechariah 4:8-10)
The exact fulfilment of Scripture prophecies is a convincing proof of their Divine original. Though the instruments be weak and unlikely, yet God often chooses such, to bring about great things by them. Let not the dawning light be despised; it will shine more and more to the perfect day. Those who despaired of finishing the work, shall rejoice when they see Zerubbabel giving directions what to do, and taking care that the work be done. It is a comfort to us that the same all-wise, almighty Providence, which governs the earth, is in particular conversant about the church. All that have the plummet in their hands, must look up to the eyes of the Lord, have constant regard to Divine Providence, act in dependence on its guidance and submission to its disposals. Let us fix our faith on Christ, and view Him carrying on his work according to his own glorious plan, and daily bringing his spiritual building nearer to completion.
Matthew Henry's Commentary on 2 Chronicles 16:9
Asa seeks the aid of the Syrians, His death.
A plain and faithful reproof was given to Asa by a prophet of the Lord, for making a league with Syria. God is displeased when he is distrusted, and when an arm of flesh is relied on, more than his power and goodness. It is foolish to lean on a broken reed, when we have the Rock of ages to rely upon. To convince Asa of his folly, the prophet shows that he, of all men, had no reason to distrust God, who had found him such a powerful Helper. The many experiences we have had of the goodness of God to us, aggravate our distrust of him. But see how deceitful our hearts are! we trust in God when we have nothing else to trust to, when need drives us to him; but when we have other things to stay on, we are apt to depend too much on them. Observe Asa's displeasure at this reproof. What is man, when God leaves him to himself! He that abused his power for persecuting God's prophet, was left to himself, to abuse it further for crushing his own subjects. Two years before he died, Asa was diseased in his feet. Making use of physicians was his duty; but trusting to them, and expecting that from them which was to be had from God only, were his sin and folly. In all conflicts and sufferings we need especially to look to our own hearts, that they may be perfect towards God, by faith, patience, and obedience.
