2 Samuel 12:23 - Joseph Benson’s Commentary on the Old and New Testaments

Wherefore should I fast Seeing fasting and prayer cannot now prevail with God for his life. I shall go to him Into the state of the dead in which he is, and into heaven, where, I doubt not, I shall find him. Or, as Mr. Saurin paraphrases the words, “If I cannot have the consolation to partake with this infant the temporal happiness wherewith the divine goodness hath blessed me, I hope to rejoin his soul one day in heaven, and to partake with him eternal felicity.” As David undoubtedly believed in the immortality of the soul, and even in the resurrection of the body, it would be quite unreasonable to leave out this latter idea, and suppose, with some commentators, that he only meant he should die and go to the grave like his son, which would be a very poor consolation. But, considered in the light here stated, his words convey the most satisfactory comfort, and “are the noblest lesson,” says Delaney, “upon all that is reasonable and religious in grief that ever was penned.”
