Why Called, The Woman is Bed?

Why Called woman is Bed?

The Woman Conceived a Man,
The Woman Born a Man,
The Woman Born an Woman,
The Woman Engaged a Man,
The Woman Married a Man
The Woman Becomes His Friend,
The Woman Blessed Continually,
The Woman's By Generation Come,
The Woman Dies, Man seek anothers Woman,
The Woman's Mouth Praise The Lord
The Woman without there would be
No-One-At-All

The Women's Faces shall be radiant
In The Court of The Lord.

So Why Called,
The Woman is Bed?
