Murmur not one against another, brethren, lest you be judged: behold, the judge stands before the door.
Jesus therefore answered and said unto them, Murmur not among yourselves.
1 Corinthians 10:10
Neither murmur you, as some of them also murmured, and were destroyed by the destroyer.
1 Peter 4:9
Practice hospitality one to another without grudging.
They also that erred in spirit shall come to understanding, and they that murmured shall learn doctrine.
And the LORD said unto Moses, Bring Aaron's rod again before the testimony, to be kept for a sign against the rebels; and you shall put away their murmurings from me, that they die not.
