John Gill Bible Commentary

Uphold me according unto thy word,.... In thy ways, that my footsteps slip not; in thine arms, and with the right hand of thy righteousness, from fainting and sinking under difficulties and discouragements, in trying circumstances; and from slipping and sliding out of the way of God; and from a total and final filling away, according to thy word of promise, that, as are the days of thy people, their strength shall be; and that thou wilt never leave them nor forsake them. The Targum is, "uphold me in thy word;'' or by thy word, either essential or written; that I may live; meaning not corporeally, though none so live but whom the Lord upholds in life; but, spiritually, live by faith on Christ the Saviour, live comfortably on the word of promise, and live honourably, agreeably to the word of God, in all holy conversation and godliness; and let me not be ashamed of my hope: as men are, when they are disappointed or having and enjoying what they have been hoping and waiting for; but the grace of hope makes not ashamed, nor shall those who have it ever have any reason to be ashamed of it; since it is a good hope through grace; is an anchor of the soul, sure and steadfast; is upon a good foundation, Christ, and by which men are saved; and so may rejoice, in full hope of the glory of God they shall certainly enjoy.
