Considered by many to be the best set of commentaries on Scripture ever produced! Calvin’s Commentaries cover the O.T. (except for Judges through Job and Proverbs through Song of Solomon) and the N.T. (except 2 and 3 John and Revelation).
The preface to the Kregal edition of Spurgeon's Commenting and Commentaries (1988) also notes, "It would not be possible for me too earnestly to press upon you the importance of reading the expositions of that prince among men, JOHN CALVIN! I am afraid that scant purses may keep you from their purchase, but if it be possible, procure them. I have often felt inclined to cry out with Father Simon, a Roman Catholic: 'Calvin possessed a sublime genius,' and with Scaliger, 'Oh! how well Calvin has reached the meaning of the prophets - no one better.' You will find 42 or more goodly volumes worth their weight in gold. Of all commentaries I believe John Calvin to be the most candid. In his expositions he is not always what some would call Calvinistic. That is to say, where Scripture maintains the doctrine of predestination and grace he flinches in no degree, but inasmuch as some Scriptures bear the impress of human free action and responsibility, he does not shun to expound their meaning in all fairness and integrity. He was no trimmer and pruner of texts. He gave their meaning as far as he knew it."
