BDBD is Psalm 42:7-8

The author imagines themself at the base of a dry waterfall in a deep mountain crevis or narrow valley. Above the Lord God has a great store of love and wealth. The Lord opens the floodgate a little releasing his cash onto the deeply depressed turmoil, the oppressed, the weak, and the weary. The bone-dry had a thirst for the Lord as the deer panting for water (1-2). Now comes the water. Now comes the relief. Refreshing Spirit to a dry soul. Deep calls to deep.

The Lord will send His endless love to the one who seeks his kingdom day and night, a song at night to comfort his soul, and prayer from dawn to dusk. All the Lord’s waves and billows of affection and passion cleanse parched flesh. Tension releases to rest. Comfort replaces restlessness. Relief for the weighed down dejected. Spirit for the dispirited. Salty tears washed away with cool fresh well water. Stench begone downstream to the ocean’s deep. The water will come. The sea brought home awaits a deep call to deep.
