Musar do Hioba 38:7

After this, during the last four hours of the night, the angels of the third watch begin reciting songs of praise. At that time the righteous of this world awaken to Hashem’s service and the angels recite, “Behold, bless Hashem, all you servants of Ha- shem who stand in the House of Hashem at night” (Ibid., 134:1). When dawn arrives, the stars and constellations begin singing in trepidation and awe, in keeping with the verse, “When the stars of the morning sang together and all the sons of God exulted” (Iyov 38:7). Afterwards, the sun appears, singing sweetly, “Acknowledge Hashem, call upon His name, tell of His deeds among the peoples” (Tehillim 105:1). At that time Israel go to the synagogue to pray and to accept upon themselves the yoke of Heaven, making their great and awesome declaration of Hashem’s unity with the words, “Hear, O Israel, Hashem is our God, Hashem is one!” (Devorim 6:4). Then the name of the Holy One Blessed is He is sanctified and unified by all the hosts of Heaven and earth, granting Him satisfaction.
