O clap your hands, all ye people; shout unto God with the voice of triumph (Psalm 47:1).
Our opening verse is talking about the shout of victory. Some people shout out of fear, but in Christianity we shout in victory. We shout unto the Lord with the voice of triumph. It’s like the shout the children of Israel gave in conquering Jericho. As they journeyed to the Promised Land, they got to Jericho, but the city was shut with thick and imposing walls (Joshua 6:1).
