NET

4 For certain men have secretly slipped in among you—men who long ago were marked out for the condemnation I am about to describe—ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.

Darby

4 For certain men have got in unnoticed, they who of old were marked out beforehand to this sentence, ungodly [persons], turning the grace of our God into dissoluteness, and denying our only Master and Lord Jesus Christ.

KJV

4 For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
