Matthew 13:15 Commentary - Abbott's Illustrated New Testament
Verse 15Lest at any time, &c., that is, their eyes and ears were wilfully closed against the truth. The sentiment of this answer of our Savior's, the meaning of which is rendered still more plain by the parallel passages, (Mark 4:11,12; Luke 8:10,) is, that, while divine truth is so revealed that the docile and spiritually-minded, and all really desirous to learn of him, can easily understand it, yet it is so presented that the captious, the proud, and the evil-minded, may hear and not understand. A veil covers and conceals the spiritual meaning, though it is a veil easily to be removed by all who wish to remove it.
