2 Corinthians 11:28

This happened because Paul adopted the habit of teaching the people entrusted to him on a daily basis. He worked during the day and taught at night, for he did not hesitate to put himself out for their sakes..

"In journeyings often, in hunger and thirst and nakedness, besides those things that are without." What is left out is more than what is enumerated. Yea rather, one cannot count the number of those even which are enumerated; for he has not set them down specifically, but has mentioned those the number of which was small and easily comprehended, saying, "thrice" and "thrice," and [again] "once;" but of the others he does not mention the number because he had endured them often. And he recounts not their results as that he had converted so many and so many, but only what he suffered on behalf of the Preaching; at once out of modesty, and as showing that even should nothing have been gained but labor, even so his title to wages has been fulfilled.

For if one that hath charge of but a single house, and hath servants and superintendents and stewards, often cannot take breath for cares, though there be none that molests him: he that hath the care not of a single house, but of cities and peoples and nations and of the whole world; and in respect to such great concerns, and with so many spitefully entreating him, and single-handed, and suffering so many things, and so tenderly concerned as not even a father is for his children-consider what he endured. For that thou mayest not say, What if he was anxious, yet the anxiety was…
