'Labors' in the Bible

in stripes, in imprisonments, in tumults, in labors, in watchings, in fastings;

not glorying beyond our measure, that is, in other men's labors; but having hope that, as your faith groweth, we shall be magnified in you according to our province unto further abundance,

Are they ministers of Christ? (I speak as one beside himself) I more; in labors more abundantly, in prisons more abundantly, in stripes above measure, in deaths oft.
