Tehillim, pronounced “the-hill-leem,” are psalms.  Reich wrote these pieces in 1981.  The words of part one are taken from Psalm 19:1-4: “The heavens declare the glory of God; and the firmament sheath his handiwork.  Day unto day uttereth speech, and night unto night sheath knowledge.”  The second part, which begins at 11:31, is Psalm 34:13-15, whose words are: “Keep your tongue from evil, and your lips from speaking deceit.  Depart from evil and do good; Seek peace and pursue it.  The eyes of the Lord are on the righteous, and His ears are open to their cry.”
