Saturday before Palm Sunday is called Lazarus Saturday or Lazaritsa and is celebrated to commemorate the resurrection of Lazarus. According to legend, Lazarus of Bethany died on Saturday and Jesus resurrected him on Sunday, on Palm Sunday. That is why Sunday is seen as a greater celebration than Saturday.  Names that celebrate this day are Lazar, Lazarka, Lazo, Cveta and all names derived from plants: Liliana, Kalina etc.According to Scripture, laws then required that one can be a teacher only if that person has reached the age of thirty years. Jesus preached his teachings for 4 years and because of the Passover, crowd came to Jerusalem to celebrate Passover and Jesus came there for the fourth time as a teacher.

But then he learned that his friend Lazarus from Bethany is ill. Jesus immediately went there but arrived four days after his death and the funeral. The sisters of Lazarus, Martha and Mary rebuked him saying that if he had arrived on time, Lazarus wouldn't have died. Martha told him: "Lord, if You had been here, my brother wouldn't have died. But I know that whatever you ask from God, God will give you. "
Scripture says that God wanted Lazarus to die, to manifest his power through him. When Jesus came to the tomb, he called Lazarus: "Lazarus, come forth." And Lazarus promptly came wrapped in canvas and with cloth around his face. Everyone who saw this, believed that Jesus is the Son of God. This act gave further glory to Jesus. And he went back to Jerusalem.
When he arrived at Mount of Olives, Jesus sent two of his disciples in Vitfagija to bring donkey (ass) and a donkey. He told them: "Go to the village in front of you and you will immediately find a tied donkey and a colt with her; Untie them and bring them to me. And if someone ask you something, you tell them Lord needs them and that he will immediately send them back ".
Students brought the donkeys, and then put
their garments on colt on which Jesus sat, thus entered Jerusalem greeted by the crowd.
This welcoming to Jesus in Jerusalem was a consequence of his great popularity among people which increased even more after the resurrection of Lazarus. The question is why Jesus entered Jerusalem riding a donkey?
Interpreters of Scripture say that in the eastern nations, donkey was a symbol of peace versus horses that were used to fight in wars. Donkey peacefully served man as Jesus served people. Crowd welcomed Jesus with flowers, willow branches and their clothing littered the road and sang: "Hosanna to the Son of David. Blessed is he who comes in the name of God. Hosanna in the highest."
