Psalms 73:17 - Joseph Benson’s Commentary on the Old and New Testaments

Until I went into the sanctuary of God Till I consulted with the oracle, or word of God. He alludes to the practice of those times, which was in dark and difficult cases to resort to God's sanctuary, and the oracle in it, for satisfaction. Then understood I their end There I learned that their prosperity was short, and would quickly have an end, and that a most terrible one; that their fair morning would be followed with a black and dreadful evening, and an everlasting night. “This is the third argument, with which we may repress the spirit of murmuring and distrust, so apt to be excited by the prosperity of the wicked; and it is one communicated to us by the word of God, which alone can acquaint us with what shall be the end, the final portion of sinners. This is an arrow from the heavenly quiver, which brings down our enemy at once, and lays Dagon prostrate before the ark.”
