John Calvin Commentary Psalms 139:24

"And see if there be any wicked way in me, And lead me in the way everlasting." — Psalms 139:24 (ASV)

And lead me, etc. I see no foundation for the opinion of some that this is an imprecation, and that David sentences himself to punishment. It is true that “the way of all the earth” is an expression used sometimes to denote death, which is common to all, but the verb here translated as lead is more commonly taken in a good than a bad sense, and I question if the phrase way of this life ever means death.

It seems evidently to denote the full continuous term of human life, and David prays God to guide him even to the end of his course. I am aware some understand it to refer to eternal life, nor is it denied that the world to come is comprehended under the full term of life to which the Psalmist alludes, but it seems enough to adhere to the plain meaning of the words, that God would watch over his servant to whom he had already shown kindness to the end, and not forsake him in the midst of his days.
