John Gill Commentary Psalms 119:116

"Uphold me according unto thy word, that I may live; And let me not be ashamed of my hope." — Psalms 119:116 (ASV)

Uphold me according to your word
In your ways, that my footsteps slip not; in your arms, and with the right hand of your 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 your word of promise, that, as are the days of your people, their strength shall be; and that you will 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.
