Psalm 82
God stands in the divine council and judges the "gods," the powers and rulers who judge unjustly. The charge is specific: defend the weak and fatherless, rescue the needy. They're called "gods" and "sons of the Most High," but they'll die like men. Jesus cites verse 6 in John 10:34-36.
"Defend the cause of the weak and fatherless; uphold the rights of the afflicted and oppressed." (Psalm 82:3)
