Then Annas sent him chained to Caiaphas, the high priest.

Because of it I am experiencing trouble, even to the point of being chained like a criminal. However, God's word is not chained.

Keep in mind those who are in chains, as if you were chained with them, and those who are in trouble, as being yourselves in the body.
