Contradiction with Matthew 6:25
Contradicts the concern for material provision in 1 Samuel 17:18 by emphasizing not to worry about physical needs.
Matthew 6:25: Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
Contradiction with Luke 12:22
Similar contradiction as Jesus advises against worrying about material needs, unlike the directive in 1 Samuel 17:18.
Luke 12:22: And he said unto his disciples, Therefore I say unto you, Take no thought for your life, what ye shall eat; neither for the body, what ye shall put on.
