'Compelled' in the Bible

And now, compelled by the Spirit and obligated by my convictions, I am going to Jerusalem, not knowing what will happen to me there,

For if I [merely] preach the gospel, I have nothing to boast about, for I am compelled [that is, absolutely obligated to do it]. Woe to me if I do not preach the good news [of salvation]!

But [all went well, for] not even Titus, who was with me, was compelled [as some had anticipated] to be circumcised, despite the fact that he was a Greek.
