Bede, on Rev 20:1

“And I saw an angel coming down from heaven, having the key of the bottomless pit, and a great chain in his hand.”

“And I saw an angel ... having the key to the abyss, etc. Recapitulating from the beginning, he more fully explains how he previously said: The beast that you saw was, and is not, and will ascend from the abyss and go into destruction (Rev. 17). Therefore, the Lord, endowed with paternal power, descended in the flesh to wage war against the prince of the world, and, having bound him, to snatch away his vessels.”
