'Lacking' in the Bible

Because the ministration of this service is not only filling up the measure of what is lacking to the saints, but also abounding by many thanksgivings to God;

And when I was present with you, and wanted, I was chargeable to no man: for that which was lacking to me the brethren which came from Macedonia supplied: and in all things I have kept myself from being burdensome unto you, and so will I keep myself.

labor and hardship,many sleepless nights, hunger and thirst,often without food, cold, and lacking clothing.
