a Bible passage
9. Cast me not off in the time of my old age. David having just now declared that God had been the protector of his life at his birth, and afterwards his foster-father in his childhood, and the guardian of his welfare during the whole course of his past existence; being now worn out with age, casts himself anew into the fatherly bosom of God. In proportion as our strength fails us — and then necessity itself impels us to seek God — in the same proportion should our hope in the willingness and readiness of God to succor us become strong. David’s prayer, in short, amounts to this: “Do thou, O Lord, who hast sustained me vigorous and strong in the flower of my youth, not forsake me now, when I am decayed and almost withered, but the more I stand in need of thy help, let the decrepitude and infirmities of age move thee to compassionate me the more.” From this verse expositors, not without good reason, conclude that the conspiracy of Absalom is the subject treated of in this psalm. And certainly it was a horrible and tragical spectacle, which tended to lead, not only the common people, but also those who excelled in authority, to turn away their eyes from him, as they would from a detestable monster, when the son, having driven his father from the kingdom, pursued him even through the very deserts to put him to death.
