37 The mouth of the righteous man utters wisdom, and his tongue speaks what is just. 31 The law of his God is in his heart; his feet do not slip. The Psalmist is teaching the way to apply the law so that it goes from his head to his heart and feet. Each Psalm teaches a philosophyThe question is how does the Palmist apply the law and what are his conclusions? He applies the law by blessing and cursing. The wicked are like grass,carry out their wicked schemes, cut off, will be no more, plot against the righteous, draw their sword, be brokenwill perish, do not pay back,cursed, cut off,condemnation,destroyed,forsaken The righteous are green plants, refrain from anger , do not fret, inherit the land, enjoy great peace, laugh at the wicked, curse is their sword turned on them, Lord upholds the righteous,will be sustained,give generously, blessed, not forsaken, exaltation, hope for future, delivered. The law pronounced is Gods work in preserving our lives by our going from one deliverance to another.
