'Bonds' in the Bible

Even as it is meet for me to think this of you all, because I have you in my heart; inasmuch as both in my bonds, and in the defence and confirmation of the gospel, ye all are partakers of my grace.

So that my bonds in Christ are manifest in all the palace, and in all other places;

And many of the brethren in the Lord, waxing confident by my bonds, are much more bold to speak the word without fear.

The one preach Christ of contention, not sincerely, supposing to add affliction to my bonds:

but those out of contention, announce the Christ, not purely, supposing to arouse tribulation for my bonds.
