John Gill Commentary Ezekiel 28:4

"by thy wisdom and by thine understanding thou hast gotten thee riches, and hast gotten gold and silver into thy treasures;" — Ezekiel 28:4 (ASV)

With your wisdom and with your understanding you have gotten
you riches

Through skill in navigation and trade, for which the Tyrians and their princes were famous, they acquired great wealth: so antichrist, by carnal policy, and hellish subtlety, has amassed vast treasures together; the sale of pardons and indulgences has brought immense riches into the pope's coffers: and have gotten gold and silver into your treasures ; in great quantities; see (Revelation 18:3Revelation 18:17) .
