"Arise, O God, judge the earth, for all the nations are Your possession." Since judges do not necessarily judge faithfully, You must judge the earth and save the oppressed from their oppressors, which is why "Arise, O God, judge the earth" is written. This means judgment of the poor and deprived people of the entire world. I am not chagrined only by the injustice committed towards the poor (of the nation of) Israel but by the oppressed and poor of all the world's nations, whose judges distort their sentence; I pray that You may judge them for You are, indeed, the LORD for all the nations in Your possession. You created them, and commanded them to be just - one of the seven (Noahide) laws. You commanded them, and You are therefore to avenge all the oppressed and sustain them in justice.
