Woe to you, Ariel, Ariel, the city where David settled! Add year to year and let your cycle of festivals go on.
Compare this with verse 11. He gives us the scroll and we can’t read it because it is sealed up. Every year they kept the cycle of festivals not realizing that they depicted bigger events that marked the ages. Jesus crucifixion was the true passover. The spirit falling on the disciples was the true Pentecost. At the end of the age we have several festivals and kick this off with the festival of trumpets.
