'Pray' in the Bible

For this reason we also, from the day we first received these tidings, have never ceased to pray for you and to entreat that you may be filled with a clear knowledge of His will accompanied by thorough wisdom and discernment in spiritual things;

And pray at the same time for us also, that God may open for us a door for preaching, for us to tell the truth concerning Christ for the sake of which I am even a prisoner.
