'Unprincipled' in the Bible

in order that we may be no longer babes, tossed and carried about by every wind of that teaching which is in the sleight of men, in unprincipled cunning with a view to systematized error;

and if He rescued righteous Lot, oppressed by the sensual conduct of unprincipled men

That is what he says in all his letters, when speaking in them of these things. In those letters there are some statements hard to understand, which ill-taught and unprincipled people pervert, just as they do the rest of the Scriptures, to their own ruin.

You therefore, beloved, knowing this beforehand, be on your guard so that you are not carried away by the error of unprincipled men and fall from your own steadfastness,
