Note 5 — ISAIAH. (continued 4)
Reading edition
The voice of the seraphim at this time was so loud and melodious, and the power of their heavenly music was so great, when extolling the holiness and glory of Jehovah that the posts, with the lintel of the door of the temple, seemed to tremble, to be shaken in the place where they stood, or loosed from their place. This was a very surprising effect (though seen only in vision); for these posts were so large and strong, that they supported gates of brass which are said to have required twenty men to shut them, on account of their ponderous weight.—Macculloch.
