Philippians 4:10-13 

I rejoice in the Lord greatly that now at last you have revived your concern for me; indeed, you were concerned for me, but had no opportunity to show it. Not that I am referring to being in need; for I have learned to be content with whatever I have. 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. I can do all things through him who strengthens me.
