Yahweh is the fountain of life (Ps 36:7-36:9)

“All people may take refuge

In the shadow of your wings.

They feast

On the abundance of your house.

You give them drink

From the river of your delights.

With you is the fountain of life.

In your light,

We see light.”

Everyone can take refuge in the shadows under the wings of Yahweh. They can feast from the abundance of his house. They get to drink from the delightful rivers. Yahweh is the foundation of life. Without him there would be no light. Actually through this light, we can see through his light.
