Isaias : Douay-Rheims Bible parallel
This inspired writer is called by the Holy Ghost, (Ecclesiastic. xlviii. 25.) the great prophet; from the greatness of his prophetic spirit, by which he hath foretold, so long before, and in so clear a manner, the coming of Christ, the mysteries of our redemption, the calling of the Gentiles, and the glorious establishment, and perpetual flourishing of the Church of Christ: insomuch that he seems to have been rather an evangelist than a prophet. His very name is not without mystery: for Isaias in Hebrew (יְשַׁעְיָהוּ) signifies the salvation of the Lord, or, Jesus is the Lord. He was, according to the tradition of the Hebrews, of the blood royal of the kings of Juda; an after a most holy life, ended his days by a glorious martyrdom; being sawed in two, at the command of his wicked son-in-law, king Manasses, for reproving his evil ways. Challoner.
— He began to prophesy ten years before the foundation of Rome, and the ruin of Nineveh. His style is suitable to his high birth. He may be called the prophet of the mercies of the Lord. Under the figure of the return from captivity, he foretells the redemption of mankind (Calmet) with such perspicuity, that he might seem to be an evangelist. St. Jerome.
