a Bible passage
51 “You stiff-necked people, uncircumcised in heart and ears, you are forever opposing the Holy Spirit, just as your ancestors used to do.
51-53. Ye stiffnecked … ye do always resist the Holy Ghost, &c.—It has been thought that symptoms of impatience and irritation in the audience induced Stephen to cut short his historical sketch. But as little farther light could have been thrown upon Israel's obstinacy from subsequent periods of the national history on the testimony of their own Scriptures, we should view this as the summing up, the brief import of the whole Israelitish history—grossness of heart, spiritual deafness, continuous resistance of the Holy Ghost, down to the very council before whom Stephen was pleading.
