'By The Spirit' in the Bible

And one of them named Agabus, rising up, signified by the spirit that a great famine was coming upon the whole habitable globe: which also came in the reign of Claudius Caesar.

Now when these things were accomplished, Paul purposed by the Spirit, passing through Macedonia and Achaia, to go to Jerusalem, saying, That after I have been there, I must see Rome also.

And now behold I am going, bound by the Spirit, unto Jerusalem, not knowing what things shall there befal me:

And finding disciples, we tarried there seven days: and they said to Paul, by the Spirit, that he should not go up unto Jerusalem.
