'Pray' in the Bible

Judge for yourselves: is it proper for a woman to pray to God with her head uncovered?

Therefore let one who speaks in a tongue pray that he may interpret.

For if I pray in a tongue, my spirit prays, but my mind is unfruitful.

What is the outcome then? I will pray with the spirit and I will pray with the mind also; I will sing with the spirit and I will sing with the mind also.
