This commentary has been called, "perhaps the best exposition of the Epistle yet to be found" (J.W.C., cited in Johnston's Treasury of the Scottish Covenant, p. 341). Charles Spurgeon comments, "By a Calvinist of the old school. Heavy, perhaps, but precious." At the very least it should be considered a classic Covenanter's commentary. John Brown of Wamphray was one of Samuel Rutherford's favorite students. He was ejected in 1662, imprisoned and cruelly treated until he suffered exile to the Netherlands -- all for steadfastly maintaining the principles of the Covenanted Reformation. While in exile he wrote thirteen books. Johnston notes that Brown "has been regarded the most important theologian of the second period of Scottish Presbyterianism" (Treasury of the Scottish Covenant, p. 339). This commentary gives us a good indication as to why Brown is so highly regarded among faithful Calvinists, godly historians and numerous commentators.
