'Widow' in the Bible

if you don't oppress the foreigner, the fatherless, and the widow, and don't shed innocent blood in this place, neither walk after other gods to your own hurt:

Thus says Yahweh: Execute justice and righteousness, and deliver him who is robbed out of the hand of the oppressor: and do no wrong, do no violence, to the foreigner, the fatherless, nor the widow; neither shed innocent blood in this place.
