The prophetic word from the Psalms pronounced upon the people.
 The pronouncement of Christ victory over the curse and the coming of the Holy Spirit.
Acts 2 'I saw the Lord always before me.Because he is at my right hand,
       I will not be shaken.
   Therefore my heart is glad and my tongue rejoices;
       my body also will live in hope,
   because you will not abandon me to the grave,
       nor will you let your Holy One see decay.
   You have made known to me the paths of life;
       you will fill me with joy in your presence.

 Peter speaks the prophetic curse against Judas.
Acts 1 20 "For," said Peter, "it is written in the book of Psalms,
   " 'May his place be deserted;
       let there be no one to dwell in it,' and,
   " 'May another take his place of leadership

The book of Psalms pronounce curses on the nations. The apostles spoke them after they had been released from prison. The apostle Paul said that if any one preaches another gospel then let them receive the curses. The church is protected by the prophetic curses.
Acts 4 24  When they heard this, they raised their voices together in prayer to God. "Sovereign Lord," they said, "you made the heaven and the earth and the sea, and everything in them.25 You spoke by the Holy Spirit through the mouth of your servant, our father David:
   " 'Why do the nations rage
       and the peoples plot in vain?
  26  The kings of the earth take their stand
       and the rulers gather together
       against the Lord
 The pronouncements of the curses brings protection to the church. They came together under the protection of the curse.
32 after they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.
32  All the believers were one in heart and mind. No one claimed that any of his possessions was his own, but they shared everything they had.33 With great power the apostles continued to testify to the resurrection of the Lord Jesus, and much grace was upon them all. There were no needy persons among them. For from time to time those who owned lands or houses sold them, brought the money from the sales and put it at the apostles' feet, and it was distributed to anyone as he had need.

The pronouncement of the creation covenant.God is ruler over the nations through the law, covenants, curses, statutes, decrees and promises. God cannot be controlled by anyone. His authority extends to all governments. 
Acts 7 48  However, the Most High does not live in houses made by men. As the prophet says:
49   " 'Heaven is my throne,
       and the earth is my footstool.
   What kind of house will you build for me? says the Lord.
       Or where will my resting place be?
50   Has not my hand made all these things?'
The pronouncements bring cursing and blessing together.  The church is built upon pronoucing the Psalms not on the organization.
54  When they heard this, they were furious and gnashed their teeth at him.55  But Stephen, full of the Holy Spirit, looked up to heaven and saw the glory of God, and Jesus standing at the right hand of God.56 "Look," he said, "I see heaven open and the Son of Man standing at the right hand of God."
 57 At this they covered their ears and, yelling at the top of their voices, they all rushed at him,    dragged him out of the city and began to stone him. Meanwhile, the witnesses laid their clothes at the feet of a young man named Saul.
