Psalm 83 is one of five Psalms that are entitled Imprecatory Psalms.  So what’s imprecation?  It involves petitioning God’s wrath upon the wicked.  They were written with righteous indignation at what was seen as defilement and blasphemy of God’s reputation and actions.  They came from that deep place of aroused anger at seeing God’s name desecrated and everything He stands for ridiculed and mocked.  They were written not out of spite or wishing for revenge, but to verbally hand the entire issue over for God to deal with…for the battle is not ours but God’s, (I Samuel 17:47 & II Chronicles 20:15) and it’s His to judge at the appointed time.
