1 Corinthians 11:4-5; 1 Corinthians 11:13; 1 Corinthians 14:13-15
Every man praying or prophesying , having his head covered, dishonoureth his head.
But every woman that prayeth or prophesieth with her head uncovered dishonoureth her head: for that is even all one as if she were shaven .
Judge in yourselves : is it comely that a woman pray unto God uncovered?
Wherefore let him that speaketh in an unknown tongue pray that he may interpret .
For if I pray in an unknown tongue, my spirit prayeth , but my understanding is unfruitful.
What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
