Psalm 23 is an account of everything God has already done for David in the past, as well as everything David is confident God will do for him in the future. But the chief end of all God's past provisions and future promises is found in the final phrase of verse 3: “...He leads me in the paths of righteousness for his name's sake.” All that God does is for “his name's sake.” In other words, all that God does is for his glory. And one if the chief ways God has chosen to bring glory to himself is by being good to his people.
