The noun din (or the verb form meaning 'to judge') denotes judgment in a legal sense, a cause or case brought before a judge, and the act of vindicating or condemning. It is used in Aramaic sections of the Bible as well as in Hebrew poetic and wisdom texts.
Din captures Israel's understanding of God as the supreme Judge whose verdicts are always righteous. The wisdom literature frequently calls on God to execute din for the poor and oppressed (Proverbs 31:8–9; Psalm 140:12). Daniel's vision climaxes in the divine throne room where the 'Ancient of Days' sits and 'the court sat in judgment' (dina yethiv, Daniel 7:10) — the ultimate tribunal before which all earthly kingdoms must answer. The eschatological dimension of din assures the oppressed that cosmic justice will prevail even when human courts fail.
