John Gill's Bible Commentary Ver. 6. For by wise counsel thou shall make thy war , etc.] Counsel, as well as strength, is necessary for war: kings and states, before they enter on a war, should not only well consider the justness of their cause, but should consult whether they have a sufficiency of men and money to carry it on; and should concert the wisest methods to attack the enemy, or defend themselves; and, above all, should ask counsel of God; (see 2 Kings 18:20 Luke 14:31,32). And this is true of our spiritual warfare with sin, Satan, the world, and false teachers; which requires not only strength to wage war with them, but wise counsel, that we may be able to understand and guard against their cunning, wiles, and stratagems: and this is principally to be asked of God, who is wonderful in counsel; and of good and experienced men, skilled in those matters; and in the multitude of counsellors [there is] safety ; to take the advice of wise counsellors, and many of them, even among men, is safe for princes and states, in the above case and in all others; and especially to ask and take counsel of God, who gives wisdom liberally to them that ask it; and of Christ, the wonderful Counsellor; and from the Scriptures, whom David made his counsellors; and from old experienced Christians, and ministers of the word, with whom are wisdom, counsel, and understanding; (see Gill on “ Proverbs 11:14”).
Matthew Henry Commentary
Verses 3-6 - Piety and prudence in outward affairs, both go together to complete wise man. By knowledge the soul is filled with the graces and comfort of the spirit, those precious and pleasant riches. The spirit i strengthened for the spiritual work and the spiritual warfare, by tru wisdom.
