Verse 4. - Grant thee according to thine own heart; i.e. whatever thy heart desireth "in connection with this expedition, all that thou hopest from it, all that thou wouldst have it accomplish." And fulfil all thy counsel; ¢.e. make all thy plans to prosper.

20:1-9 This psalm is a prayer for the kings of Israel, but with relation to Christ. - Even the greatest of men may be much in trouble. Neither the crown on the king's head, nor the grace in his heart, would make him free from trouble. Even the greatest of men must be much in prayer. Let none expect benefit by the prayers of the church, or their friends, who are capable of praying for themselves, yet neglect it. Pray that God would protect his person, and preserve his life. That God would enable him to go on in his undertakings for the public good. We may know that God accepts our spiritual sacrifices, if by his Spirit he kindles in our souls a holy fire of piety and love to God. Also, that the Lord would crown his enterprises with success. Our first step to victory in spiritual warfare is to trust only in the mercy and grace of God; all who trust in themselves will soon be cast down. Believers triumph in God, and his revelation of himself to them, by which they distinguish themselves from those that live without God in the world. Those who make God and his name their praise, may make God and his name their trust. This was the case when the pride and power of Jewish unbelief, and pagan idolatry, fell before the sermons and lives of the humble believers in Jesus. This is the case in every conflict with our spiritual enemies, when we engage them in the name, the spirit, and the power of Christ; and this will be the case at the last day, when the world, with the prince of it, shall be brought down and fall; but believers, risen-from the dead, through the resurrection of the Lord, shall stand, and sing his praises in heaven. In Christ's salvation let us rejoice; and set up our banners in the name of the Lord our God, assured that by the saving strength of his right hand we shall be conquerors over every enemy.Grant thee according to thine own heart,.... Which is to see his seed, the travail of his soul, and to have the pleasure of the Lord prosper in his hand; to have all his people called, preserved, and glorified;

and fulfil all thy counsel; whatever was agreed upon in the council and covenant of peace between him and his Father, relating to his own glory, and the salvation of his people.
