Philippians 4:10-12

10But I rejoiced in [the] Lord greatly, that now however at length ye have revived your thinking of me, though surely ye did also think [of me], but lacked opportunity.

11Not that I speak as regards privation, for as to me I have learnt in those circumstances in which I am, to be satisfied in myself.

12I know both how to be abased and I know how to abound. In everything and in all things I am initiated both to be full and to be hungry, both to abound and to suffer privation.
