Verse 4. - Rejoice the soul of thy servant. The prayer rises from mere entreaties for relief and recovery from a state of suffering, into an earnest request for that which the heart of man is ever longing for and seeking after - gladness and joy. The faithful are promised that they shall come ultimately to a condition of exceeding great joy; but even saints are sometimes impatient, and want their joy in this world and at once. For unto thee, O Lord, do I lift up my soul (comp. Psalm 25:1, entitled, like this, "a Psalm of David"). There is no more likely way of attaining to spiritual joy than to be always lifting up the soul to God.

86:1-7 Our poverty and wretchedness, when felt, powerfully plead in our behalf at the throne of grace. The best self-preservation is to commit ourselves to God's keeping. I am one whom thou favourest, hast set apart for thyself, and made partaker of sanctifying grace. It is a great encouragement to prayer, to feel that we have received the converting grace of God, have learned to trust in him, and to be his servants. We may expect comfort from God, when we keep up our communion with God. God's goodness appears in two things, in giving and forgiving. Whatever others do, let us call upon God, and commit our case to him; we shall not seek in vain.Rejoice the soul of thy servant,.... With the discoveries of love, of pardoning grace, and mercy, before made sad with sin or sufferings; and with the light of God's countenance, before troubled with the hidings of his face: this may be applied to Christ, in sorrowful circumstances, who was made full of joy with his Father's countenance, Matthew 26:37.

for unto thee, O Lord, do I lift up my soul: in prayer, as the Targum adds; and it denotes the devotion, fervency, heartiness, and sincerity, of his prayer; the doing of it with a true heart, the lifting up of the heart with the hands unto God, Lamentations 3:41 or by way of offering unto the Lord, not the body only, but the soul or heart also; or as a depositum committed into his hands; so Christ lifted up his eyes, and his heart and soul, to his divine Father; and also made his soul an offering for sin, and at death commended his spirit into his hands, John 17:1; see Gill on Psalm 25:1.
