'In Labor' in the Bible

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

As for Titus, remember that he is a partner of mine, and is also my associate in labors for you. As for the other brothers, remember that they are delegates from the churches, men in whom Christ is glorified.

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.

in labor and travail, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.
