Adam Clarke on Psalms 41:8

An evil disease, say they, cleaveth fast unto him - דבר בליעל יצוק בו debar beliyaal yatsuk bo, a thing, word, or pestilence of Belial, is poured out upon him. His disease is of no common sort; it is a diabolical malady.

He shall rise up no more - His disease is incurable without a miracle; and he is too much hated of God to have one wrought for him. Some apply this to the death and resurrection of Christ; he lieth - he is dead and buried; he shall never rise again from the dead.
