  "Speak to the children of Israel, saying: 'In the seventh month, on the first day of the month, you shall have a sabbath-rest, a memorial of blowing of trumpets, a holy convocation. You shall do no customary work on it; and you shall offer an offering made by fire to the LORD.'"

  To the Chief Musician. On an instrument of Gath. A Psalm of Asaph.

  Sing aloud to God our strength;
  Make a joyful shout to the God of Jacob.
  Raise a song and strike the timbrel,
  The pleasant harp with the lute. Blow the trumpet at the time of the New Moon,
  At the full moon, on our solemn feast day.
