question: What is the specific word repeated many times before the phrase is continued, "vor sein Angesicht"?
context: The first movement corresponds to the opening movement of a symphony, which is often in sonata form. The movement sets the first two verses of the psalm, which call for three actions: "jauchzet" (rejoice), "dienet" (serve), and "kommt" (come). The three topics match two contrasting themes of the exposition of the sonata form, and its development. They are followed by a recapitulation of the two themes.
  A timpani roll on C of two measures leads to an orchestral D major chord in the third measure, marked ff (fortissimo), and a syncopated entry of the choir one beat later, pronouncing in unison "Jauchzet, jauchzet" (Rejoice, rejoice), the first topic. The choir first sings a motif a fourth downwards, while the strings add a turn motif (Doppelschlag-Motiv) which gets repeated throughout the piece and finally opens a theme of the double fugue in Part 4. The short motifs are treated to upward sequences, then continued in upward scales in triplets, again in sequences, then another upward line in dotted rhythm, but no melody, rendering only the repeated word "jauchzet" with different expression. Fred Kirshnit, who introduced the piece for a performance of the American Symphony Orchestra, regarded the treatment as an "orchestral explosion". The text is continued in measure 16 by "dem Herrn alle Welt" (to the Lord, [of] the whole world).The following verse begins with "Dienet" (Serve), the second topic. It is quiet, marked sostenuto and pp (pianissimo). It has been compared to the second theme of the sonata form. From the lowest voice to the highest, the material is expanded in imitation, with all voices divided. The phrase "Dienet dem Herrn" is first sung by the alto, and then imitated by the other voices. "Dienet dem Herrn mit Freuden" appears first in the lower voices while the sopranos expand the theme one measure later, marked espressivo and crescendo. Joyful groups of sixteenths appear, first in single voices, then in denser texture, leading to the first topic, "Jauchzet". In measure 111 the third topic appears, "Kommt". This word is repeated many times before the phrase is continued, "vor sein Angesicht" (before his face), later also "mit Frohlocken" (with shouts of joy). In measure 130, a reprise of the first section leads to a close of the movement in a unison "alle Welt", with a fermata on every syllable.
