He maketh rivers into a wilderness, and water-springs into dry ground;

He maketh the wilderness into a pool of water, and the dry land into water-springs;

Who made the rock into a water-spring, and the hard stone into a fountain.

May he be like rain that falls on the cut grass,
like spring showers that water the earth.

As they pass through the Baca Valley, he provides a spring for them. The rain even covers it with pools of water.
