Salmos 1

Salmos 1:3

The streams from the divine Spirit resemble watering by rivers: just as they cause trees planted near them to flourish, so the spiritual streams are the cause of bearing divine fruit. For this very reason Christ the Lord called his own teaching water.… Appropriately, then, blessed David compared the person devoted to the divine sayings with trees growing on riverbanks, ever green, bearing fruit in season. — COMMENTARY ON THE PSALMS 1:7-8
