In this Psalm of intercession, the Psalmist pleads with God for revival and the restoration of His people. Israel is depicted as a vine which God brought out of Egypt and planted. It wasn't long until the vine flourished and spread. However, due to the sin of Israel, the wall of God's protection collapsed leaving the vine open to attacks from the enemy.
Three times the Psalmist prays, "Turn us again." This is always the prayer of God's people preceding revival and restoration.
