Spiritual principles of worship of and relationship with God - Psalm 99

Psalm 99 (Listen)

99:1   The LORD reigns; let the peoples tremble!
    He sits enthroned upon the cherubim; let the earth quake!
2   The LORD is great in Zion;
    he is exalted over all the peoples.
3   Let them praise your great and awesome name!
    Holy is he!
4   The King in his might loves justice.
    You have established equity;
  you have executed justice
    and righteousness in Jacob.
5   Exalt the LORD our God;
    worship at his footstool!
    Holy is he!
6   Moses and Aaron were among his priests,
    Samuel also was among those who called upon his name.
    They called to the LORD, and he answered them.
7   In the pillar of the cloud he spoke to them;
    they kept his testimonies
    and the statute that he gave them.
8   O LORD our God, you answered them;
    you were a forgiving God to them,
    but an avenger of their wrongdoings.
9   Exalt the LORD our God,
    and worship at his holy mountain;
    for the LORD our God is holy!
