'Widowhood' in the Bible

She took off of her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of Enaim, which is by the way to Timnah; for she saw that Shelah was grown up, and she wasn't given to him as a wife.

She arose, and went away, and put off her veil from her, and put on the garments of her widowhood.

David came to his house at Jerusalem; and the king took the ten women his concubines, whom he had left to keep the house, and put them in custody, and provided them with sustenance, but didn't go in to them. So they were shut up to the day of their death, living in widowhood.

but these two things shall come to you in a moment in one day, the loss of children, and widowhood; in their full measure shall they come on you, in the multitude of your sorceries, and the great abundance of your enchantments.

"Don't be afraid; for you shall not be ashamed: neither be confounded; for you shall not be disappointed: for you shall forget the shame of your youth; and the reproach of your widowhood you shall remember no more.
