Charles Ellicott Commentary Job 33:23

"If there be with him an angel, An interpreter, one among a thousand, To show unto man what is right for him;" — Job 33:23 (ASV)

To show to man his uprightness. —Some render, “to show to man what is right for him,” but it seems rather to mean, to declare concerning that man his uprightness, to plead his cause before God and be his advocate. (Compare 1 Kings 14:13; 2 Chronicles 19:3, and similar passages.)

This angel, who is one among a thousand and discharges the function of an interpreter, is a remarkable anticipation of the existence of that function with God which is discharged by the Advocate with the Father (1 John 2:1; Romans 8:34; Hebrews 7:25). It is impossible for us who believe that all Scripture is given by inspiration of God not to see in this an indication of what God intended afterwards to teach us concerning the intercession and mediation of the Son and the intercession of the Holy Spirit on behalf of humankind (Romans 8:26). (Compare John 14:16.)
