This plague is distinctly attributed here and in Exodus 12:23 to the personal intervention of the Lord; but it is to be observed that although the Lord Himself passed through to smite the Egyptians, He employed the agency of “the destroyer” Exodus 12:23, in whom, in accordance with Hebrews 11:28, all the ancient versions, and most critics, recognize an Angel (compare 2 Kings 19:35; 2 Samuel 24:16).
