'Prayer' in the Bible

Do not keep back from one another what is right, but only for a short time, and by agreement, so that you may give yourselves to prayer, and come together again; so that Satan may not get the better of you through your loss of self-control.

Every man who takes part in prayer, or gives teaching as a prophet, with his head covered, puts shame on his head.

Be judges yourselves of the question: does it seem right for a woman to take part in prayer unveiled?

For if I make use of tongues in my prayers, my spirit makes the prayer, but not my mind.

What then? let my prayer be from the spirit, and equally from the mind; let my song be from the spirit, and equally from mind.

For if you give a blessing with the spirit, how will the man who has no knowledge say, So be it, after your prayer, seeing that he has not taken in what you are saying?
