Matthew 6:25
That is why I say to you, Do not be anxious about your life here--what you can get to eat or drink; nor yet about your body-- what you can get to wear. Is not life more than food, and the body than its clothing?
1 Corinthians 10:10
And do not murmur, as some of them murmured, and so 'were destroyed by the Angel of Death.'
Philippians 2:14
In all that you do, avoid murmuring and dissension,
Jude 1:16
These men are always murmuring, and complaining of their lot; they follow where their passions lead them; they have arrogant words upon their lips; and they flatter men for the sake of what they can get from them.
