'Often' in the Bible

We have sent with them our brother, whom we have often tested and found diligent in many things, but now even more diligent because of his great confidence in you.

Are they servants of Christ?—I speak as if insane—I more so; in far more labors, in far more imprisonments, beaten times without number, often in danger of death.

I have been in labor and hardship, through many sleepless nights, in hunger and thirst, often without food, in cold and exposure.
