Then loud wailing would resume with fresh fervour. Some would throw ashes and dirt over their heads and clothes, while others methodically ripped their outer garments. Jewish funerals were a seven day extravaganza of despair and grief. When Jesus arrived they were into their fourth day of anguished laments. There was no singing, only weeping and wailing and blaming.
Death is final.
When Jesus joined that festival of death and despair, He wept. He saw people listening to Satan's lie that death is final. They led him to the burial place of Lazarus. It was a cave with a-stone laid across the entrance. Graves and tombs have an air of finality about them.
