Charles Ellicott Commentary Psalms 50:23

"Whoso offereth the sacrifice of thanksgiving glorifieth me; And to him that ordereth his way [aright] Will I show the salvation of God." — Psalms 50:23 (ASV)

Offers praise. —Better, sacrifices thanksgiving, as in Psalms 50:14; the poet here sums up what he has previously said. This clause must therefore be considered as addressed to the sincere formalist, the next to the openly wicked.

To him that orders ... —Literally, as the text stands, places his way, which is hardly intelligible. The version of Symmachus suggests the reading tam, instead of sam, “to him who walks uprightly.” But being plainly intended for the ungodly, we look for some mention of amendment in this clause; and if the poet wrote shab, we get, literally, him who has turned his way, i.e., who has changed his course of life.
