To judge the fatherless and the oppressed, that the man of the earth may no more oppress.
To judge the fatherless - to vindicate them from wrong.
That the man of the earth may no more oppress. The Hebrew expresses confidence rather than desire (which would require the abbreviated future). So "that the man of the earth" (literally, the weak mortal х 'ªnowsh (H582)] of the earth, as opposed to the God of heaven) shall not continue to terrify [so the Hebrew, `aarats (H776)]. In Isaiah 47:12, the same Hebrew is translated "prevail."
