Justice

This last verse [Deut 10:19] contains a key idea: the care given by the community to its weakest members, and even to those who are not members at all, is to be a mirror of God’s own care for the Israelites when they were enslaved. The activities of the community are not undertaken on general principles; they arise out of the lively remembrance of God’s just and merciful initiatives with them (“A wandering Aramean was my father” — Deut. 26:5).

Because justice is such a central part of God’s nature, he has declared enmity against every form of injustice. His wrath will come upon those who have exploited the poor and weak; he will not permit his purpose to be subverted.—Fleming Rutledge, The Crucifixion, 110
