Rejoice the soul of thy servant - Cause me to rejoice; to wit, by thy gracious interposition, and by delivering me from danger and death.
For unto thee, O Lord, do I lift up my soul - Compare the notes at Psalm 24:4. The idea is that of arousing himself, or exerting himself, as one does who makes strenuous efforts to obtain an object. He was not languid, or indifferent; he did not put forth merely weak and fitful efforts to find God, but he bent his whole powers to that end; he arouses himself thoroughly to seek the divine help. Languid and feeble efforts in seeking after God will be attended with no success. In so great a matter - when so much depends on the divine favor - when such great interests are at stake - the whole soul should be roused to one great and strenuous effort; not that we can obtain his favor by force or power, and not that any strength of ours will prevail of itself, but
(a) because nothing less will indicate the proper intensity of desire; and
(b) because such is his appointment in regard to the manner in which we are to seek his favor.
Compare Matthew 7:7-8; Luke 13:24; Luke 16:16.

Rejoice the soul of thy servant - I want spiritual blessings; I want such consolations as thou dost impart to them that love thee; I present that soul to thee which I wish thee to console.

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.

lift up my soul--with strong desire (Psalm 25:1).
