'Widow' in the Bible

if you do not oppress the transient and the foreigner, the orphan, or the widow, and do not shed innocent blood [by oppression and by unjust judicial murders] in Jerusalem, nor follow after other gods to your own ruin,

Thus says the Lord, “Execute justice and righteousness, and rescue the one who has been robbed from the hand of his oppressor. And do no wrong; do no violence to the stranger, the fatherless, or the widow, nor shed innocent blood in this place.
