There is lots in the Bible on this subject. Here are a few verses:
Jesus answered and said to them, "Do not grumble among yourselves. John 6:43
But Jesus, conscious that His disciples grumbled at this, said to them, "Does this cause you to stumble?
John 6:61
The Pharisees and their scribes began grumbling at His disciples, saying, "Why do you eat and drink with the tax collectors and sinners?" Luke 5:30
Show hospitality to one another without grumbling. 1 Peter 4:9
Then Moses said to Aaron, "Say to all the congregation of the sons of Israel, 'Come near before the LORD, for He has heard your grumblings.'" Exodus 16:9
“How long shall this wicked congregation grumble against me? I have heard the grumblings of the people of Israel, which they grumble against me. Numbers 14:27
Obviously, grumbling is wrong. The opposite is giving praise to God, which is what Paul says to do continually, especially in prayer. I will ask God to work on me about this and when I feel like grumbling, I will try to praise instead.
