Jerome : (Verse 19). The meek will obtain fresh joy in the Lord, and the neediest people will exult in the Holy One of Israel. But when the blind or those who are initiated into mystical matters have first beheld these things or have lifted up their eyes from blindness and darkness to see, so that true light may arise for those sitting in darkness and the shadow of death, then the meek, of whom it is written: Blessed are the meek, for they shall inherit the earth (Matt. V, 4), whether they be the poor, of whom the leader says in the Psalms: This poor man cried out, and the Lord heard him (Ps. XXXIII, 7); and he who judges the poor people and will save the children of the poor (Ps. XIII, 9), of whom it is said to the Jews: You have despised the counsel of the poor, they shall add joy in the Lord, so that he who glories, may glory in the Lord (II Cor. X); and poor men or those in despair and contempt by men, who did not have knowledge of the law before, will exult in the Holy One of Israel, who says: Be holy, for I am holy (Lev. XI, 44). — Commentary on Isaiah
