'Be Not Deceived' in the Bible

Or know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with men,

Be not deceived: Evil companionships corrupt good morals.

Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.

Be not deceived, my beloved brethren.
