Yirmeyah 22:3

Thus saith HASHEM; Execute ye mishpat (justice) and tzedakah (righteousness), and save the plundered out of the yad of the oshek (oppressor); and do no wrong, do no violence to the ger (alien), the yatom (orphan), nor the almanah (widow), neither shed dahm naki (innocent blood) in this makom (place).
