Psalms 23:2. He maketh me to like down in green pastures means he has created everything that would make live a life that is worth it. Green pasture means everything good . This is to say everything good has been made available for me as it is at my finger tips. Green pastures means freshness, I dont have to wait for remnant because I have access to first hand blessing. HALLELUYAH.
He leads me beside the still water: This means he had calm all my troubles, everything I should be worried about has been solved by God. So the calm water signifies settlement of all anxiousness, worries, fear, doubt. All he has made calm.
