1 Timothy 4:2 in the King James Version
Speaking lies in hypocrisy; having their conscience seared with a hot iron;
Context
1 But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons,
2 through the hypocrisy of men who speak lies, branded in their own conscience as with a hot iron,
3 forbidding marriage and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth.
