The Hijab in the Bible 
The Hijab is not something new. Muslim women follow the example of righteous women in the past such as Mary, the mother of Jesus. Some of the evidence from the bible includes the following two verses.
“And every woman who prays or prophesies with her head uncovered dishonors her head.”1 Corinthians 11:3-6
“I also want women to dress modestly, with decency and propriety, not with braided hair or gold or pearls or expensive clothes, but with good deeds, appropriate for women who profess to worship God.” 1 Timothy 2:9-10
🌹 The Hijab is Confidence : 
The Hijab enables women to have confidence in themselves as human beings. It increases the self-esteem of women by allowing them to focus on what really matters in life.
 The obsession with physical appearance can have dangerous and unhealthy consequences, as some women go to harmful lengths in order to feel accepted by an increasingly demanding society. The Hijab helps prevent such mental and physical harms associated with a lack of confidence, by limiting self-consciousness based on appearance.
“I don’t wear it because I am oppressed, I wear it because I am empowered.”Joumana, 23, Melbourne
Quran 24:31
And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.
