“Lastly, there follows the reason why I say this: "for You are my patience" [Psalm 71:5]. Now if He is patience rightly, He is that also which follows, "O Lord, my hope from my youth." My patience, because my hope: or rather my hope, because my patience. "Tribulation," says the Apostle, "works patience, patience probation, but probation hope, but hope confounds not." [Romans 5:3-5] With reason in You I have hoped, O Lord, I shall not be confounded for everlasting. "O Lord, my hope from my youth." From your youth is God your hope? Is He not also from your boyhood, and from your infancy? Certainly, says he. For see what follows, that you may not think that I have said this, "my hope from my youth," as if God noways profited mine infancy or my boyhood; hear what follows: "In You I have been strengthened from the womb." Hear yet: "From the belly of my mother You are my Protector" [Psalm 71:6]. Why then, "from my youth," except it was the period from which I began to hope in You? For before in You I was not hoping, though You were my Protector, that led me safe unto the time, when I learned to hope in You. But from my youth I began in You to hope, from the time when You armed me against the Devil, so that in the girding of Your host being armed with Your faith, love, hope, and the rest of Your gifts, I waged conflict against Your invisible enemies, and heard from the Apostle, "There is not for us a wrestling against flesh and blood, but against principalities, and powers," etc. [Ephesians 5:12] There a young man it is that does fight against these things: but though he be a young man, he falls, unless He be the hope of Him to whom he cries, "O Lord, my hope from my youth." "In You is my singing always." Is it only from the time when I began to hope in You until now? Nay, but "alway." What is, "alway"? Not only in the time of faith, but also in the time of sight. For now, "So long as we are in the body we are absent from the Lord: for by faith we walk, not by sight:" [2 Corinthians 5:6] there will be a time when we shall see that which being not seen we believe: but when that has been seen which we believe, we shall rejoice: but when that has been seen which they believed not, ungodly men shall be confounded. Then will come the substance whereof there is now the hope. But, "Hope which is seen is not hope. But if that which we see not we hope for, through patience we wait for it." [Romans 8:24] Now then you groan, now unto a place of refuge you run, in order that you may be saved; now being in infirmity you entreat the Physician: what, when you shall have received perfect soundness also, what when you shall have been made "equal to the Angels of God," [Matthew 22:30] will you then perchance forget that grace, whereby you have been delivered? Far be it.”

“By thee have I been holden up from the womb,.... Supported in being, upheld in life, and sustained with food and raiment, and followed with the mercies and blessings of life from thence to this present moment; which the psalmist takes notice of, as he does of what goes before and follows after, to encourage his faith and hope in God as to present deliverance; thou art he that took me out of my mother's bowels; See Gill on Psa 22:9; the Syriac version is, "thou art my hope from my mother's bowels"; the Arabic version, "thou art my helper"; and the Septuagint and Vulgate Latin versions, "thou art my protector"; the word is only used here, and in Psa 90:10; and is there rendered "cut off"; the Lord was, as it were, his "cutter off" (t); that cut the navel string, and loosed him from his mother, and safely brought him into the world, and preserved him ever since: wherefore he adds, my praise shall be continually of thee; as the God of nature and providence; and also as the God of grace, who had blessed him both with temporal and spiritual blessings; and these being continued with him, he determines that God should be the subject of his praise always. The Targum is, "in thy Word my praise is continually.'' (t) "excisor meus", Gejerus.”
