Ezekiel 23:6 in the World English Bible
who were clothed with blue—governors and rulers, all of them desirable young men, horsemen riding on horses.
Context
5 And Aholah played the harlot when she was mine; and she doted on her lovers, on the Assyrians her neighbours,
6 Which were clothed with blue, captains and rulers, all of them desirable young men, horsemen riding upon horses.
7 Thus she committed her whoredoms with them, with all them that were the chosen men of Assyria, and with all on whom she doted: with all their idols she defiled herself.
