My son, do not forget my teaching,
    but let your heart keep my commandments,
  for length of days and years of life
    and peace they will add to you.
  Let not steadfast love and faithfulness forsake you;
    bind them around your neck;
    write them on the tablet of your heart.
  So you will find favor and good success
    in the sight of God and man.
  Trust in the LORD with all your heart,
    and do not lean on your own understanding.
  In all your ways acknowledge him,
    and he will make straight your paths.

— Proverbs 3:1-6

25 “Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing? 26 Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? 27 And which of you by being anxious can add a single hour to his span of life? 28 And why are you anxious about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin, 29 yet I tell you, even Solomon in all his glory was not arrayed like one of these. 30 But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, O you of little faith? 31 Therefore do not be anxious, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. 33 But seek first the kingdom of God and his righteousness, and all these things will be added to you.

34 “Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Sufficient for the day is its own trouble.

— Matthew 6:25-34
