The Psalmist in his moments of idealization does justice to both of these concepts in his songs of law and equity. Indeed Psalm 119 could be paraphrased in a volume of its own. The people tremble caught twixt law and equity.
Strength loves judgement.
Thus vengeance and forgiveness sit between the cherubim. Counsel, plead my cause. Defender, stand up for me, fight for me my fight. Take hold of shield and buckler, Draw out the spear, stop the way. Save me by thy name judge me by thy mighty power give ear to my words.
