'Murmurers' in the Bible

And the people were as murmurers,'speaking evil in the ears of Jehovah: and when Jehovah heard it, his anger was kindled; and the fire of Jehovah burnt among them, and devoured in the uttermost part of the camp.

And the erring in spirit have known understanding, And murmurers learn doctrine!'

These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage.
