Genesis 15:14 - Coke's Commentary on the Holy Bible

Will I judge— Judge is a Hebraism for punish: 2 Chronicles 20:12.Hebrews 13:4. It is also used in the contrary sense, of acquitting, rewarding, or redressing wrongs, when applied to the righteous, Psalms 10:18. The reason is evident: God, the just Judge, when he tries both righteous and wicked, may properly be said to judge, either in the sense of condemning or acquitting, as his judgment is, and always must be, perfectly right.
