Norm MacDonald here with a summary of Psalms 4. This chapter is a prayer of David to God, asking Him to hear his cries and have mercy on him. He asks God to be gracious and to provide him with peace and joy. David also warns the wicked that they will not prosper and asks God to judge them. In conclusion, David thanks God for hearing his prayer. In short, David wants God to listen to his prayer, judge the wicked, and give him peace and joy.
