¹² Beware, brothers, lest perhaps there might be in any one of you an evil heart of unbelief, in falling away from the living God;

¹⁵ looking carefully lest there be any man who falls short of the grace of God, lest any root of bitterness springing up trouble you, and many be defiled by it,

¹⁷ You therefore, beloved, knowing these things beforehand, beware, lest being carried away with the error of the wicked, you fall from your own steadfastness.
