As obedient children, not fashioning yourselves according to the former lusts in your ignorance:
Ver. 14. Not fashioning yourselves] συσχηματιζομενοι. As a player is fashioned to the obscene speeches and carriages of him whom he is impersonateting.
In your ignorance] Men may remain grossly ignorant amidst abundance of means, as these Jews did. "Who is blind but my servant? or deaf as my messenger?" &c., Isaiah 42:19,20 .
