Luther on Hebrew & Greek

“Let us be sure of this: we will not long preserve the gospel without the languages. The languages are the sheath in which this sword of the Spirit [Eph. 6:17] is contained; they are the casket in which this jewel is enshrined; they are the vessel in which this wine is held; they are the larder in which this food is stored. . . . If through our neglect we let the languages go (which God forbid!), we shall . . . lose the gospel.”
