Ezekiel 26:17
17
And they shall take up a lamentation for thee, and say to thee, How art thou destroyed, that wast inhabited by sea-faring men, the renowned city, which wast strong in the sea, she and her inhabitants, who cause their terror to be on all that haunt it!
Mighty
'Mighty,' as in Revelation 19:18, signify people who are educated about doctrine derived from the Word. By extension, 'mighty' signifies education or learning derived there.
