7. “The words of the Lord” are “pure words” (ver. 6). This is in the person of the Prophet himself, “The words of the Lord” are “pure words.” He says “pure,” without the alloy of pretence. For many preach the truth impurely; for they sell it for the bribe of the advantages of this life. Of such the Apostle says, that they declared Christ not purely. “Silver tried by the fire for the earth.” These words of the Lord by means of tribulations approved to sinners. “Purified seven times:” by the fear of God, by godliness, by knowledge, by might, by counsel, by understanding, by wisdom. For seven steps also of beatitude there are, which the Lord goes over, according to Matthew, in the same sermon which He spake on the Mount, “Blessed” are “the poor in spirit, blessed the meek, blessed they that mourn, blessed they which do hunger and thirst after righteousness, blessed the merciful, blessed the pure in heart, blessed the peacemakers.” Of which seven sentences, it may be observed how all that long sermon was spoken. For the eighth where it is said, “Blessed” are “they which suffer persecution for righteousness’ sake,” denotes the fire itself, whereby the silver is proved seven times. And at the termination of this sermon it is said, “For He taught them as one having authority, and not as their scribes.” Which refers to that which is said in this Psalm, “I deal confidently in Him.”
