Isaiah 55:2; Philippians 4:11-12

Why do you spend your money for that which is not bread,
    and your labor for that which does not satisfy?
Listen carefully to me, and eat what is good,
    and delight yourselves in rich food.

11 Not that I am referring to being in need; for I have learned to be content with whatever I have. 12 I know what it is to have little, and I know what it is to have plenty. In any and all circumstances I have learned the secret of being well-fed and of going hungry, of having plenty and of being in need.
