Adam Clarke on 1 Samuel 2:33

And the man of thine - Of this passage Calmet observes: "The posterity of Eli possessed the high priesthood to the time of Solomon; and even when that dynasty was transferred to another family, God preserved that of Eli, not to render it more happy, but to punish it by seeing the prosperity of its enemies, to the end that it might see itself destitute and despised. This shows the depth of the judgments of God and the grandeur of his justice, which extends even to distant generations, and manifests itself to sinners both in life and death; both in their own disgrace, and in the prosperity of their enemies."
