'Imprisonment' in the Bible

And I am justified in having this confidence about you all, because, both during my imprisonment and when I stand up in defence of the Good News or to confirm its truth, I have you in my heart, sharers as you all are in the same grace as myself.

and the greater part of the brethren, made confident in the Lord through my imprisonment, now speak of God's Message without fear, more boldly than ever.

while the others proclaim Him from motives of rivalry, and insincerely, supposing that by this they are embittering my imprisonment.
