'Murmur' in the Bible

The men whom Moses sent to investigate the land, who returned and made the whole community murmur against him by producing an evil report about the land,

Therefore you and all your company have assembled together against the Lord! And Aaron -- what is he that you murmur against him?"

And the staff of the man whom I choose will blossom; so I will rid myself of the complaints of the Israelites, which they murmur against you."
