אחת שאלתי מאת יי
Achat sha’alti mei-et Adonai
One thing I have asked from Adonai
David implies that of all the things a person, even a father of children and a king of a nation, might ask of God, one thing has been his central desire.
If we know clearly what we want and seek in that focusing of desire to have it, our lives will be more fulfilling to the extent that the one thing we choose is worthwhile.
David chose worship in the nearness of God’s Presence as the one thing. David marveled at the very idea of the Divine Presence above the Ark, the connection between heaven and earth. It is a theme in the story of his life in the books of Samuel.
If all of our desires could be concentrated down to one thing, what would we choose? How would we formulate our request? To be single-minded (in a proper sense, not in a fruitless obsession) is a good thing. One thing is needed.
