Matthew 6:25
For this cause I tell you, Be not anxious about your life, what ye shall eat, or what ye shall drink; nor for your body, what ye shall put on. Is not the life of more value than meat, and the body than raiment?
1 Corinthians 10:10
Neither murmur ye, as some of them also murmured, and perished by the destroyer.
Philippians 2:14
Do all things without murmurings or disputes:
Jude 1:16
These men are murmurers, complainers at their lot in life, walking after their own corrupt passions; and their mouth utters hyperbolically pompous expressions, pretending high personal admiration, in order to make their advantage.
