Leviticus 23 —tells us what they did

  1. On the fifteenth day of the seventh month, when you gather in the produce of the land, you must celebrate a pilgrim festival of the LORD for seven days. On the first day is a complete rest and on the eighth day is complete rest.
  2. On the first day you must take for yourselves branches from majestic trees—palm branches, branches of leafy trees, and willows of the brook—and you must rejoice before the LORD your God for seven days.

Haggai 2

  1. On the twenty-first day of the seventh month, the LORD spoke again through the prophet Haggai:
  2. “Ask the following questions to Zerubbabel son of Shealtiel, governor of Judah, the high priest Joshua son of Jehozadak, and the remnant of the people:
  3. ‘Who among you survivors saw the former splendor of this temple? How does it look to you now? Isn’t it nothing by comparison?
  4. Even so, take heart, Zerubbabel,‘says the LORD. ‘Take heart, Joshua son of Jehozadak, the high priest, and all you citizens of the land,’ says the LORD, ‘and begin to work. For I am with you,‘says the LORD who rules over all.
  5. ‘Do not fear, because I made a promise to your ancestors when they left Egypt, and my spirit even now testifies to you.’
  6. Moreover, the LORD who rules over all says: ‘In just a little while I will once again shake the sky and the earth, the sea and the dry ground.
  7. I will also shake up all the nations, and they will offer their treasures; then I will fill this temple with glory,‘says the LORD who rules over all.
  8. ‘The silver and gold will be mine,‘says the LORD who rules over all.
  9. ‘The future splendor of this temple will be greater than that of former times,’ the LORD who rules over all declares, ‘and in this place I will give peace.’ ”

Isaiah 12

  1. At that time you will say:
    “I praise you, O LORD,
    for even though you were angry with me,
    your anger subsided, and you consoled me.
  2. Look, God is my deliverer!
    I will trust in him and not fear.
    For the LORD gives me strength and protects me;
    he has become my deliverer.”
  3. Joyfully you will draw water
    from the springs of deliverance.

Isaiah 48

  1. Leave Babylon!
    Flee from the Babylonians!
    Announce it with a shout of joy!
    Make this known!
    Proclaim it throughout the earth!
    Say, ‘The LORD protects his servant Jacob.
  2. They do not thirst as he leads them through dry regions;
    he makes water flow out of a rock for them;
    he splits open a rock and water flows out.’

Joel 3

  1. On that day the mountains will drip with sweet wine,
    and the hills will flow with milk.
    All the dry stream beds of Judah will flow with water.
    A spring will flow out from the temple of the LORD,
    watering the Valley of Acacia Trees.

Joel 2

  1. After all of this
    I will pour out my Spirit on all kinds of people.
    Your sons and daughters will prophesy.
    Your elderly will have revelatory dreams;
    your young men will see prophetic visions.

Isaiah 44

  1. “Now, listen, Jacob my servant,
    Israel whom I have chosen!”
  2. This is what the LORD, the one who made you, says —
    the one who formed you in the womb and helps you:
    “Don’t be afraid, my servant Jacob,
    Jeshurun, whom I have chosen!
  3. For I will pour water on the parched ground
    and cause streams to flow on the dry land.
    I will pour my Spirit on your offspring
    and my blessing on your children.
