God's care all the year round has been very rich, and he wants to give more blessings to people. To be crowned is to pile grace on people's heads.
The poet described God as if he were sitting in a car surrounded by clouds. No matter where his rut passes, his rich love is like fat.
"path": the original "car trace"; God is like riding across a field. Everywhere he went, showers moistened the earth and made the fields rich.
Beautiful and prosperous flowers, fruits and grains are like the crown of the year.
