3 If any man teaches another doctrine and does not agree with the wholesome* instruction,+ which is from our Lord Jesus Christ, nor with the teaching that is in harmony with godly devotion,+ 4 he is puffed up with pride and does not understand anything.+ He is obsessed* with arguments and debates about words.+ These things give rise to envy, strife, slander,* wicked suspicions, 5 constant disputes about minor matters by men who are corrupted in mind+ and deprived of the truth, thinking that godly devotion is a means of gain.+

9 Do not be led astray by various and strange teachings, for it is better for the heart to be strengthened by undeserved kindness than by foods,* which do not benefit those occupied with them.+

17 You, therefore, beloved ones, having this advance knowledge, be on your guard so that you may not be led astray with them by the error of the lawless people and fall from your own steadfastness.*+
