'Liars' in the Bible

fornicators, sodomites, slave-dealers, liars and false witnesses; and for whatever else is opposed to wholesome teaching

One of their own number--a Prophet who is a countryman of theirs--has said, "Cretans are always liars, dangerous animals, idle gluttons."

I know your doings and your toil and patient suffering. And I know that you cannot tolerate wicked men, but have put to the test those who say that they themselves are Apostles but are not, and you have found them to be liars.

I will cause some belonging to Satan's synagogue who say that they themselves are Jews, and are not, but are liars--I will make them come and fall at your feet and know for certain that I have loved you.

But as for cowards and the unfaithful, and the polluted, and murderers, fornicators, and those who practise magic or worship idols, and all liars--the portion allotted to them shall be in the Lake which burns with fire and sulphur. This is the Second Death."
