Matthew 6:25
"For this reason I say to you, do not be anxious about your life, inquiring what you shall eat or what you shall drink, nor yet for your body, inquiring what you shall wear. Is not your life more than its food, and your body than its clothing?
1 Corinthians 10:10
nor murmur, as some of them did, and were destroyed by the Destroying Angel.
Philippians 2:14
Do everything without grumbling and disputes,
Jude 1:16
For these are murmurers, always complaining. They always go where their passions lead, and their mouth speaks great swelling words, while they pay court to men for the sake of the advantage they can get.
