Head-Covering

In Bible times both men and women wore a cloth around their head as a head-covering.

In Old Testament times men kept their head covered mainly as protection from the sun. In most cases, they wrapped a cloth around their heads like a kind of turban.
In New Testament times certain groups of Jews also kept their heads covered for religious reasons, for example while praying. Paul says, by the way, in 1 Corinthians 11:4 that a man must not cover his head when praying or speaking in the church.

When outdoors, women always kept their heads covered. They often wore a kind of turban, like the men. They might also pull their robe over their head or they wore a separate, shorter head-scarf.
Paul emphasises in 1 Corinthians 11: 2-16 that it is compulsory for women to cover their heads.
