'Murmur' in the Bible

And the people murmur against Moses, saying, 'What do we drink?'

And all the company of the sons of Israel murmur against Moses and against Aaron in the wilderness;

And in the morning, then ye shall see the glory of the LORD; for that he heareth your murmurings against the LORD: and what are we, that ye murmur against us?

And Moses said, This shall be, when the LORD shall give you in the evening flesh to eat, and in the morning bread to the full; for that the LORD heareth your murmurings which ye murmur against him: and what are we? your murmurings are not against us, but against the LORD.

and the people thirst there for water, and the people murmur against Moses, and say, 'Why is this? -- thou hast brought us up out of Egypt, to put us to death, also our sons and our cattle, with thirst.'
