'Sojourner' in the Bible

if ye oppress not the sojourner, the fatherless, and the widow, and shed not innocent blood in this place, neither walk after other gods to your own hurt:

O thou hope of Israel, the Saviour thereof in the time of trouble, why shouldest thou be as a sojourner in the land, and as a wayfaring man that turneth aside to tarry for a night?

Thus saith Jehovah: Execute ye justice and righteousness, and deliver him that is robbed out of the hand of the oppressor: and do no wrong, do no violence, to the sojourner, the fatherless, nor the widow; neither shed innocent blood in this place.
