In his biography of Bach, Martin Geck quotes a number of notes that Bach penned in the “Calov Bible,” a copy of Luther’s translation that belonged at one time to the theologian Abraham Calov.

On Miriam and her singing women, he writes, “First prelude to be performed in two choruses to the honor of God.”

Regarding the Levitical chorus and orchestra in Chronicles: “This chapter is the true foundation of all church music pleasing to God.” (Unfortunately, Geck doesn’t tell us which chapter this is.)

Also on Chronicles: “A splendid proof that along with other institutions of the church service, music from the spirit of God especially was also ordained by David” and “In a devotional service, God is always present with his grace.”
