The Rewards of Reading the Old Testament

I shall never forget my surprise when I first discovered that St. Paul's "If thine enemy hunger, give him bread", etc., is a direct quotation from... (Proverbs 25, 21). But this is one of the rewards of reading the Old Testament regularly. You keep on discovering more and more what a tissue of quotations from it the New Testament is; how constantly Our Lord repeated, reinforced, continued, refined, and sublimated, the Judaic ethics, how very seldom He introduced a novelty. - C. S. Lewis Reflections on the Psalms
