'Praying' in the Bible

We give thanks to God the Father of our Lord Jesus Christ, praying always for you,

For this cause, we also, since the day we heard this, don't cease praying and making requests for you, that you may be filled with the knowledge of his will in all spiritual wisdom and understanding,

praying together for us also, that God may open to us a door for the word, to speak the mystery of Christ, for which I am also in bonds;
