'Widows' in the Bible

I have let their widows be increased in number more than the sand of the seas: I have sent against them, against the mother and the young men, one who makes waste in the heat of the day, causing pain and fears to come on her suddenly.

For this cause, let their children be without food, and give them over to the power of the sword; and let their wives be without children and become widows; let their men be overtaken by death, and their young men be put to the sword in the fight.

Put in my care your children who have no father, and I will keep them safe; and let your widows put their faith in me.
