כֹּ֣ה ׀ אָמַ֣ר יְהוָ֗ה עֲשׂ֤וּ מִשְׁפָּט֙ וּצְדָקָ֔ה וְהַצִּ֥ילוּ גָז֖וּל מִיַּ֣ד עָשׁ֑וֹק וְגֵר֩ יָת֨וֹם וְאַלְמָנָ֤ה אַל־תֹּנוּ֙ אַל־תַּחְמֹ֔סוּ וְדָ֣ם נָקִ֔י אַֽל־תִּשְׁפְּכ֖וּ בַּמָּק֥וֹם הַזֶּֽה׃
Thus saith the LORD: Execute ye justice and righteousness, and deliver the spoiled out of the hand of the oppressor; and do no wrong, do no violence, to the stranger, the fatherless, nor the widow, neither shed innocent blood in this place.
