Luke

As they were about to take Paul into the barracks, he asked the commander, “May I say something to you?” “Do you speak Greek?” he replied.

37. May I speak unto thee? Paul offered himself to defend his cause, which all the servants of God must do. For we must do our endeavor to make our integrity known to all men, lest through our infamy the name of God be blasphemed.

Matthew Henry Presbyterian @wholebiblehenry

We have here Paul brought into a captivity which we are not likely to see the end of; for after this he is either hurried from one bar to another, or lies neglected, first in one prison and then in another, and can neither be tried nor bailed. When we see the beginning of a trouble, we know not either how long it will last or how it will issue.
