'Toil' in the Bible

For you remember, believers, our labor and hardship. We worked night and day [practicing our trade] in order not to be a [financial] burden to any of you while we proclaimed the gospel of God to you.

For this reason, when I could no longer endure the suspense, I sent someone to find out about your faith [how you were holding up under pressure], for fear that somehow the tempter had tempted you and our work [among you] would prove to be ineffective.
