'Disgraceful' in the Bible

If a woman does not cover her head, she should have her hair cut off; and if it is disgraceful for a woman to have her hair cut off or her head shaved, she should cover her head.

If there is anything they want to learn [that is, if they have questions about anything being said or taught], they are to ask their own husbands at home; for it is improper for a woman to talk in church.

But we have renounced the disgraceful things hidden because of shame; not walking in trickery or adulterating the word of God, but by stating the truth [openly and plainly], we commend ourselves to everyone’s conscience in the sight of God.
