Adam Clarke on Psalms 41:11

By this I know that thou favorest me - If thou hadst not been on my side, I had perished by this disease; and then my enemies would have had cause to triumph.

This also has been applied to our Lord; and Calmet says it is the greatest proof we have of the divinity of Christ, that he did not permit the malice of the Jews, nor the rage of the devil, to prevail against him. They might persecute, blaspheme, mock, insult, crucify, and slay him; but his resurrection confounded them; and by it he gained the victory over sin, death, and hell.
